The chainsaw does not start - reasons and solutions

The Stihl chainsaw is a device from one of the famous German developers, the Stihl company, which guarantees quality, ergonomics, maneuverability and operator comfort in working with the tool, as well as excellent performance, despite its compact size. The range of technical capabilities of the Shtil chainsaw allows you to solve problems at both professional and household levels. Saws of this brand have more than enough advantages, but, like all complex equipment, there are some disadvantages.

Why does the Shtil chainsaw not start when it's hot? Why does a chainsaw have trouble starting?

Main reasons:

fuel and air filters;
reduced compression;
carburetor adjustment;
spark plug;
ignition coil;
gap between the ignition coil and the flywheel;

Let's look at each reason in more detail.

Fuel and air filter

Contamination of the main filter elements of a chainsaw negatively affects its operation.

For example, a dirty air filter will not provide enough air to the carburetor, which will affect the quality of the air-fuel mixture and normal engine starting. A dirty fuel filter will make it difficult or even cut off the flow of gasoline to the carburetor and make it impossible for the engine to operate.

Reduced compression

One of the common cases of difficult starting of a chainsaw is wear of the CPG (cylinder-piston group).

As you know, for a chainsaw to start normally, compression must be present in its engine. It is necessary for normal compression of the fuel mixture in the engine cylinder, and it also affects the operation of the fuel pump.

During the operation of the tool, the compression value drops and the chainsaw begins to have difficulty starting.

The reasons for the lack of compression or its decrease may be natural, because The engine wears out during operation. Problems can also be caused by a serious breakdown, for example, a scuffed CPG, or a broken piston ring.

A sign of low compression is weak starter resistance when starting. With reduced compression, a decrease in the power of the chainsaw is observed, which negatively affects its performance. The problem is eliminated by replacing the piston rings, or the entire CPG.

Carburetor adjustment

Incorrect carburetor adjustment will cause the chainsaw to not develop full power. It will be difficult to start, or not start at all. Carburetor settings directly affect the quality of the air-fuel mixture, which is necessary for normal starting and further operation of the engine.

If the carburetor is incorrectly adjusted, there will be more or less gasoline in the fuel-air mixture than required, and the mixture will not ignite even with normal sparking.

Excess gasoline in the mixture is usually called overflow. A characteristic sign of overflow is a wet spark plug, after several unsuccessful attempts to start the chainsaw.

Spark plug

The spark plug is one of the main elements of the ignition system. A spark is formed at its electrodes, and if this element fails, starting will be difficult or not possible at all.

The spark plug may fail completely, or work intermittently or produce a weak spark. Checking the spark plug is quite simple; to do this, you need to unscrew it from the engine, attach it to the cap of the high-voltage wire and, placing it on the cylinder, pull the starter. If the spark plug is in order, the spark will be powerful with a bluish tint. A weak spark with a reddish tint is a sign of a problem. A defective spark plug needs to be replaced.

Ignition coil

The reason that a new chainsaw does not start, or starts poorly, may be the ignition coil. Modern chainsaws are equipped with electronic ignition coils. This part cannot be repaired, and, as a rule, if there is a defect, it is completely replaced.

Gap between ignition coil and flywheel

An incorrectly set gap between the flywheel and the ignition coil contacts affects the quality of spark formation, which in turn is responsible for normal starting and stable operation of the engine.

Repair of cylinder-piston group (CPG)

If the chainsaw engine does not start or cannot develop normal power, it is likely that there is not enough pressure in the engine cylinder to burn the fuel mixture. The reason for this may be wear and tear of elements - piston, rings, bearings, etc. In order to assess the condition of this unit, it should be visually inspected after first removing the muffler.

For a more complete diagnosis, a compression gauge is placed in the spark plug hole of a two-stroke chainsaw engine. It is used to measure compression in the engine. Based on the test results, one can judge the condition of the CPG, but accurate facts can only be obtained by completely disassembling the unit.

If the piston is chipped or scratched, it will obviously have to be replaced. The same applies to deformed or broken piston rings - for normal engine operation they must be fully functional and free of carbon deposits.

Why the chainsaw won’t start - reasons and solutions

Each model has its own weaknesses. Some saws require regular carburetor adjustments. The disadvantage of others is the chain lubrication system. Be that as it may, any breakdown can be fixed with your own hands if you figure out what its cause is and what its signs are.

What to do if the chainsaw stalls when you press the gas?

As a rule, owners of chainsaws begin to encounter this breakdown after the first 6 months of intensive use of the tool. There may be several reasons for this malfunction.

Their list includes:

using a fuel mixture prepared in the wrong proportion. If you regularly pour low-quality gasoline into the tank of a chainsaw, in which too much or too little oil is mixed, the tool will not start. In this case, you will need to drain the fuel and also dry the engine cylinder. To do this, you need to sharply pull the starter cable several times. After this, you need to fill in properly prepared fuel and start the saw engine;
Filling the spark plug with oil when starting the engine. This problem can be solved by removing, cleaning and drying the candle. After 30 minutes, the candle will dry and you can screw it in. After this you will need to start the chainsaw;
no spark. This indicates poor contact between the factory high-voltage wire and the spark plug tip. If the contact is not broken, but there is still no spark, then you need to check the electronic unit of the chainsaw’s ignition system. This element cannot be repaired, so it will need to be completely replaced;
air filter clogged. This element of the saw must be regularly cleaned of debris, small insects and dust. Otherwise, air will not enter the carburetor, where it should enrich the fuel mixture. As a result, the saw will stop starting. To solve the problem, you will need to clean the filter or replace it.

In most cases, a chainsaw stops starting due to the use of low-quality fuel and motor oil. There is no need to skimp on working fluids, as this will lead to complex and time-consuming repairs.

Checking the carburetor and signs that it needs adjustment

Correct operation guarantees maximum efficiency of the chainsaw, that is, it is possible to develop full power with the most economical consumption of the fuel mixture. Adjustment of this unit is usually carried out by the manufacturer, but its design provides for the possibility of adjustment during operation.

The fact that such adjustment will have to be made by the owner of the chainsaw is evidenced by:

Strong vibrations or damage to the protective cap.
CPG wear.
Carburetor clogged.
Inability to start the engine or its spontaneous stopping after starting.
Increased fuel consumption and exhaust emissions with a simultaneous decrease in engine power.

The chainsaw carburetor is adjusted in strict accordance with the manufacturer’s instructions using three special screws, which are responsible for the maximum (“M”) and minimum (“L”) speeds, as well as engine idle speed (“T”). In order to exclude unwanted interference by an inexperienced user in the operation of the carburetor, some manufacturers install only one idle screw.

How to start a chainsaw correctly - follow the instructions

Before you move on to studying the causes and repairs of chainsaw malfunctions, you need to understand whether you are starting to work with your chainsaw correctly. After all, it is precisely because the tool is not started correctly that its engine stalls or does not start at all.

Start the chainsaw strictly according to the instructions in the operating instructions. The procedure is as follows:

First, engage the chainsaw's chain brake by pushing its lever away from you;
Remove the protective cover from the tool tire;
Press the decompression valve, if provided in the design of the chainsaw. This will make starting the engine much easier;
If the design of the chainsaw includes a fuel pump for manual pumping, press it several times;
Place the combination throttle lever in cold start mode. To do this, lock the throttle trigger and lower the lever to its lowest position;
Place the saw on a flat surface, removing any foreign objects from under its bar;
Hold the chainsaw with both hands, placing your left hand on the handle and your right hand grasping the trigger cable. Place the toe of your right foot into the “eye” at the back of the chainsaw;
Slowly pull the cable towards you until you feel resistance. Then quickly pull the cable towards you several times until you hear the motor start briefly;
Move the throttle lever to the middle position;
Pull the cable again several times until the engine starts;
As soon as the engine starts running, sharply press the gas trigger and hold it for several seconds. At this time, move the throttle lever to its highest position;
Raise the saw from the ground without touching the gas lever;
Pull the chain brake handle towards you;
Raise the saw over old newspaper to make sure there is oil flowing to the chain. If small spots of oil appear on the paper, then you can start working.

Starting a cold engine after storage for 2 days or more or after purchase in a store.

When you purchase gas equipment from the right store, they can tell you everything in detail about the startup and operation of the gas tool, and they will also demonstrate it in practice. If this was not the case, it means it was a hypermarket or you were served by yesterday’s schoolboy or student - our congratulations!

Cold start of the engine - set the choke lever (switch) to the “choke closed” position. We pump the mixture into the carburetor if there is a fuel priming pump (primer). Pull the starting handle (starter cord) until you feel resistance from the engine, then pull vigorously (with the amplitude of your hand reaching your chest). 2-5 such movements and the engine should start and stall - this is usually what happens. If this does not happen, then, as in the case of a successful first launch, we still move the choke lever to the half-throttle position or even to the working position. And we continue the establishment in this mode with the same movements (1-4 times). It usually starts. If the saw does not start here, you need to calm down, take a breath for 2-3 minutes and try to start it in the same working position again. It starts normally.

And finally, some gas powered tools have a regular key switch for the ignition, just check to see if it's turned on.

Chainsaw Shtil stalls: reasons

If the tool turns off immediately after starting, it means that some device or part has broken down. To determine the cause, the mechanism is tested independently or in service workshops. Sometimes the reason that the mechanism does not start well is improper maintenance of the saw:

insufficient amount of gasoline;
poorly prepared fuel mixture;
poor quality of lubricant;
muffler clogged with combustion products;
unadjusted carburetor;
obstruction of the air filter;
piston or cylinder failure.

When you press the gas

The sawing units operate at idle speed, but the chain saw stalls when the gas is pressed, as the load increases. Before use, warm up the tool by running the engine at idle speed for a minute. If this is neglected, the motor stops after pressing the pedal. Other reasons may be:

clogged or unregulated fuel mixing unit;
a clogged air filter does not provide the required air flow when the load increases;
a dirty gasoline filter does not allow the required amount of mixture to pass through;
the cylinder and piston walls rub.

A low octane number of fuel causes brakes, since this circumstance prevents the engine from achieving the required power when the load increases.

At idle

Violation of the functionality of the fuel unit system leads to air leaks. In this case, the unit stalls at idle and does not maintain its number. Additional suction reduces the air impulse to the fuel pump and passes through the sump membrane or crankshaft seals. Diagnostics is done with a vacuum gauge.

Stopping the engine when cold occurs for other reasons:

the spark plug channel contains an excess amount of combustible mixture;
the gap between the tip of the spark plug and the high-voltage cradle is not adjusted;
power supply failure.

Check the seals by pouring gasoline into the crankcase; the leak is visible visually. This means that the engine does not operate at idle speed, and at high frequencies, leaky oil seals will lead to bearing jamming. If elements leak, they are replaced with new ones and sealed.

Full speed ahead

Sometimes the engine stalls after normal operation

To establish the cause, pay attention to the accompanying circumstances:

The engine stalls in the middle of operation for no apparent reason. The starter is in a stationary position and does not turn. This means that the tool is jammed and requires urgent repair.
During normal operation, power decreases in a short time and the engine stops, the cylinders are overheated. The situation indicates an air leak under the rubber pipe between the carburetor cylinder, possibly due to a rupture. The air becomes depleted of fuel; the pipe needs to be replaced.

Not gaining momentum

Many mechanism systems are involved in the startup, so the loss of speed of the Stihl chainsaw after idling can be a consequence of various factors. Reliable idling and interruptions in the engine under load can occur for the following reasons:

development of engine life;
wear, deformation and corrosion of the piston group;
malfunction of the ignition coil or spark plug;
unbalance of carburetor screws.

If the tool does not develop speed, then the conductivity of the hole in the fuel tank cap is impaired. The occurrence of a vacuum does not provide the required amount of fuel, so the engine does not gain the required power. The speed decreases when carbon dioxide accumulates in the muffler, and the removal of combustion gases is difficult.

Doesn't slow down

The tool quickly reaches maximum speed without losing power. This situation is explained by the fact that:

the throttle valve does not work due to a weakened spring or traction element;
the switch on switch periodically fails;
there is no corkscrew on the throttle axis;
the carburetor is clogged;
The fuel hose and gasoline filter are not functioning properly.

Features and technical characteristics of the Shtil 211 saw

The reliability and performance of this chainsaw is ensured by high-quality materials and workmanship.
The main working parts are made of forged steel, the cylinder is chrome-plated, the plastic of the protective casing is strong and designed for high loads. The basic modification of the Stihl MS 211 14 chainsaw has a two-stroke engine running on a mixture of gasoline and oil. The proportion is standard for 2-stroke engines - the ratio of gasoline to oil is 50:1.

The tool also has the following technical characteristics:

power – 2.3 l. With.;
chain pitch - 3/8 inch;
chain thickness – 1.3 mm;
number of chain links – 50;
fuel tank capacity – 270 ml;
tire length – 35 cm;
weight – 4.3 kg.

Another modification of the Stihl MS 211 16 chainsaw differs only in the increased length of the bar, which is 40 cm.

Why does the chainsaw stall?

If the chainsaw starts and stalls, the reasons may be different. An external inspection should be carried out before attempting to repair the instrument.

If the saw stalls during operation, you should check the presence of a mixture of oil and gasoline in the tank. If the fuel mixture runs out, the device will not work. In situations where there is still gasoline left, you should evaluate the quality of the tool before turning it off. The appearance of extraneous sounds and the subsequent sudden stop should alert you.

The formation of carbon deposits on the electrodes can also cause difficulties in the operation of the tool. You should carefully inspect the device and clean it if necessary.

When you press the gas

In cases where the chainsaw stalls when you press the gas, you should check the muffler and fuel filter. A possible cause of the problem is a leak in the fuel hoses. In some cases, adding speed helps.

Sometimes checking all the details does not give results, the tool suffocates, chokes when gas is added. If the device stalls when a person presses the gas, it is possible that the fuel supply is insufficient for normal operation. This phenomenon occurs due to a clogged carburetor or filter.

Damage can also occur due to the air filter becoming clogged with dust. When you give gas, the device stops working. You should not fix the problem yourself, since each model has individual characteristics.

The problem may be caused by insufficient or lack of lubrication on the chainsaw chain. If the chain is dry, you should clean the channels through which oil is supplied to the device bus. If the oil leaks, there are cracks and defects in the pipes, they need to be treated with sealant.

Under load

In situations where the device stalls under load, the problem may be with the gas tank or filters. Check the fuel quality and change the filter.

Often the saw does not gain speed due to the fact that the mixture poured into the gas tank has a low octane number. There is not enough power, sufficient heating is not possible, the chainsaw stalls under load.

Often, malfunctions of components lead to the device stalling under load. Hoses, seals, and gaskets should be checked for leaks. If parts are faulty, you can try to repair or replace them.

In cases where the chainsaw starts and immediately stalls, there is not enough fuel, the device does not heat up. The device must be recharged

It is important to use the correct mixture. Different types of fuel are better suited for different models

It is necessary to read the instructions, recommendations, reviews of people for whom the device works normally.

Idling

In situations where the chainsaw stalls at idle, you need to inspect the condition of the muffler. If the part is dirty, exhaust gases are poorly removed, the engine cannot continue to work and stops.

The saw stalls at idle and in cases where the carburetor is not configured correctly. For beginners, it is better to entrust the repair to specialists, since there is a possibility of incorrect settings, due to which the tool will not be able to work. A tachometer is required to adjust the carburetor.

At high speeds

If the device stalls at high speeds, pay attention to the condition of the gasoline and air filters, the serviceability of the fuel hoses

A dirty air filter can be washed under warm running water.

It is important to thoroughly dry the part before installing it so that water does not damage the serviceability of the tool.

If fluid stops flowing through the fuel hose, it is clogged. You can clean the part or replace it with a new one.

In cases where the saw stalls at high speeds, but the liquid completely flows through the hose, and the air filter is clean and in good working order, look for the cause of the breakdown in the fuel filter. Replace it with a new one or clean it.

In some cases, the problem is hidden in the gasoline pump. When a component wears out, fuel begins to leak through the walls. If this phenomenon is observed, a new pump should be installed.

When tilted

If the saw does not develop speed when tilting, turns off, or stops working, you need to check the fuel level in the tank. If it is not too high, the device in an inclined position is not supplied with sufficient fuel, since the fuel pipe is above the mixture level.

Diagnostic stages

When a chainsaw refuses to start, it is necessary to diagnose all components. The correct sequence of checks is the key to timely elimination of the problem.

Quality and correct fuel supply

If gasoline is at the bottom of the tank, check whether the fuel drive is lowered into it. On some models, the “disease” is the disconnection of the supply hose, so check it first.

The quality of the fuel is of no small importance. Manufacturers recommend using AI-92 gasoline and special two-stroke oil

It is contraindicated to pour into engine oil or waste.

The manufacturer indicates the ratio of oil and gasoline in the instructions. Violation of proportions reduces the service life and prematurely disables the chainsaw.

The gasoline-oil mixture for refueling tools can be stored for no more than 15 days. Then the oil precipitates and the channels and jets become clogged.

Spark on the candle

Ignition of the fuel is impossible without supplying a high-quality spark, so the second stage of startup diagnostics is checking the ignition.
Components that have exhausted their service life produce a weak spark, so the saw does not start well. The procedure for checking a node:

The candle is unscrewed, placed on the cylinder and connected to the candlestick.
Turn on the ignition and pull the starter.
If the spark is continuous, the spark plug is working.
If the cutting is intermittent or absent at all, the part must be replaced.

At the same time, check the gap between the contacts. Its value should be from 0.5 - 1 mm. In this case, the specific size of the gap is indicated in the instructions.

Basic information about the condition of the candle is obtained from its appearance:

Black carbon deposits – incorrect carburetor adjustment. The reason is a lack of air and an excess of fuel in the cylinders.
The spark plug is wet - the entire ignition system is faulty or too much fuel is entering the cylinder.
Red soot – there is an excess of additives in gasoline.

Filter status

Clean filters are the key to long service life for your chainsaw.

A common problem with chainsaw operation is a clogged air filter. Manufacturers recommend cleaning this unit regularly using a compressor. A clogged filter prevents air from flowing into the carburetor. As a result, excess fuel causes the spark plug to become flooded and stop producing a spark.

The fuel filter in the gas tank may also become clogged. If damaged, it must be replaced. The service life of a fuel filter depends on many factors. But the main thing is the quality of fuel and oil.

How does breather affect the saw plant?

One of the important parts of the chainsaw is the pressure regulator in the fuel tank - the breather. It is a valve that allows air to pass in one direction. When the outlet of a part becomes clogged, air does not enter the tank and the pressure inside increases.

Diagnosis of the breather is carried out in the following sequence:

Unscrew the gas tank cap. If air escapes, the pressure regulator is faulty.
Screw on the lid and start the saw. If the engine starts and immediately stalls, the breather needs to be cleaned.

One of the options for checking the operation of the unit is to monitor the flow of fuel from a disconnected hose. If gasoline flows out continuously, it means the part is working properly. A weak, intermittent stream indicates a blockage.

A small blockage can be removed with a needle without dismantling. If the breather is clogged thoroughly, you will have to remove it and carry out a thorough cleaning.

Muffler or exhaust duct clogged

Carbon deposits are systematically deposited on these components. It needs to be cleaned regularly, but most owners forget to do this. As a result, while the tool is operating, combustion products have nowhere to go, and the engine does not start or suddenly stalls.

The following factors contribute to increased carbon deposits:

Poor quality fuel.
Violation of the proportions of oil and gasoline.

If a newly purchased saw does not start when using high-quality fuel, the tool should be returned to the seller immediately. Most likely, there is a manufacturing defect in the saw, and self-diagnosis will lead to loss of warranty.

Why the chainsaw does not start, reasons and solutions. How the mechanism works

Almost all tools, both foreign (Husqvarna, Makita, Shtil, Partner 350), and Chinese chainsaws, and domestic (Druzhba, Ural), are designed the same. Therefore, finding the reason why the device does not start and stalls will not be difficult.

There are four elements where problems may arise:

The fuel for which the carburetor is responsible;
Lubrication;
The air that enters through the air filter;
A spark, the quality of which depends on the ignition unit.

They all depend on each other and interact with each other. If any element does not work correctly, the saw stops working.

Let's start with the fact that all tools start up differently - hot and cold. Two commonly used mechanisms are responsible for this process.

Be sure to look at what is written in the user manual. It states that when turning it on, you need to make sure that the emergency stop brake is engaged. But starting a saw with a brake is much more difficult, so sometimes it’s better not to turn on the brake.

As you can find out from the instructions, inside the body there is a fuel tank and an engine, and outside there is a saw part (bar with chain), a handle and a starter.

First you need to figure out exactly how the tool won’t start. For example, the saw starts up, but immediately stalls, or loses power and cutting quality.

Perhaps interruptions in operation occur due to problems in the engine. But I would not recommend disassembling it right away. It is better to look for the problem from the simplest option.

It is very important to consider the quality of the fuel. If the mixture is prepared incorrectly or has deteriorated over time, then even such reliable tools as the Ural or Husqvarna 145 will not work

The instructions must indicate the proportions and special oil specifically for your chainsaw.

Another common problem is that the user fills the candle during startup. It needs to be inspected; if it is completely dry, then fuel is not passing into the cylinder.

If you see black carbon deposits or a lot of fuel, then the carburetor may not be properly regulating the fuel supply.

If your saw tool starts, but immediately stalls, then the problem needs to be looked for in the carburetor jet or fuel filter. Perhaps they are clogged.

To check if the breather is damaged, you need to disconnect the fuel hose from the carburetor and see if the fuel mixture leaks out of it.

If the saw does not start when hot, then the problem may be in the muffler. Sometimes it gets clogged from the exhaust itself.

Quite often, saw breakdowns occur due to a small amount of chain lubricant. This happens when the channels are clogged or the oil line is leaking.

Also inspect the connections of the pipes with the oil pump fittings to see if they are leaking.

It is very bad when a breakdown occurs in the cylinder. When examining it, you may find unevenness or chips, and this may be the cause of the problem.

Briefly about the main thing

This model is the pride of the German manufacturer and is a straight tool designed for minor work. It can be used for a maximum of twenty hours per month. This beautiful device will help you manage the care of your garden, prepare firewood for winter (see How to cut down a tree), clear areas and become an indispensable assistant in other areas, say, simple manipulations.

We can say that this is a mini chainsaw model since it has a light weight of 3.9 kg

, it does not have a large tank mass, both oil and fuel. The manufacturer equips it with enough power for easy operation.

In addition, it is quite quiet, as the noise level does not exceed 98 dB during operation. To better understand the volume level, compare it to spoken language, which is 76 dB.

The power of this model is 2.6 W

. It's worth noting that this is a pretty significant level of strength considering this is not a professional chainsaw. The oil tank has a volume of only 0.145 liters, and the fuel tank. 0.25 liters. The tire measures 350mm and has a height of 0.325 inches.

Spark plug problem

A problem with spark plugs is one of the most common causes of chainsaw breakdowns!

This is one of the most common reasons why the engine stalls when cold. As a rule, its electrodes are covered with a layer of corrosion and carbon deposits, as a result of which the distance between their ends decreases - and there is ultimately no room for a spark to jump through.

The cause of corrosion and carbon deposits on the electrodes is uneven fuel supply, which is already a problem with the carburetor, which can be solved separately. There doesn’t have to be soot on the spark plug - there may be no spark because the fuel completely fills it when it’s hot, which also indicates problems with the carburetor.

The spark plug itself must be removed, dried and checked to see how the spark passes through it:

First, remove the wire and unscrew the spark plug.
Return the wire end to its original position.
Place the spark plug on the cylinder with the skirt.
Check for a spark by starting with the starter.

If there was a spark in this way, then you need to immediately move on to the problem with the carburetor. If not, then the spark plug must either be cleaned of rust and carbon deposits, or replaced. It is also possible that adjusting the distance between the electrode contacts will help.

Other reasons for the lack of spark include:

The final check for problems with the spark plugs can be completed with a number of simple procedures, after which the chainsaw should start:

Unscrew the spark plug and give it a full inspection.
Clean it from rust and deposits, dry it
Place the ends of the electrodes at the correct distance.
Drain all excess fuel from the engine of the tool so that the ignition compartment does not flood.
Place the spark plug back and try lighting again.

If these procedures helped and the saw began to work and the chain began to move, then you can work like this for about 5-30 minutes until the spark plug floods again

It is important to understand that this solution is temporary and just indicative. The main problem lies in the carburetor.

The question with him is ambiguous: in any case, it is necessary to adjust the fuel supply, but how to do this - yourself or with the help of a mechanic - is up to you.

When setting up the carburetor, be sure to use a tachometer, which will allow you to find out the number of engine revolutions with greater accuracy.

Based on them, you can already adjust its operating mode by adjusting the tightness of the screws on the carburetor block in several scenarios:

A complete inspection of the carburetor is necessary if it was not possible to determine a specific problem, but there is confidence that the jamming of the saw is associated with this particular part.

The audit is carried out as follows:

It is necessary to remove all communications (wires and hoses) from the device;
Carry out cleaning and purging. It is better to do this without removing the carburetor;
Remove the product and clean it a second time so that no traces of fuel or oil remain inside;
Gradually disassemble the device, guided by the drawing in the documentation or drawing up a diagram yourself;
All channels must be blown out with compressed air, and parts must be washed in an industrial solvent;
Give the parts at least 2 hours to dry;
Reassemble the carburetor, strictly following the instructions in the documents and diagram;
Connect back.

What to do if the chainsaw picks up speed and stalls?

This situation is very similar to the previous one, the only difference is that there the chainsaw does not demonstrate high speeds at all, but here it initially produces them, but does not maintain them. Most often, a chainsaw stalls when heating up due to clogged filtration parts of the saw, as well as malfunctions of the fuel pump.

The air filter is periodically washed and dried before reinstallation, and the fuel supply hoses should be constantly checked for leaks and, if necessary, replaced with new ones. Each part has an expiration date, so you should not be surprised that the gasoline pump will no longer hold fuel and begins to leak, which is also worth taking into account when troubleshooting such equipment.

There is a spark, the spark plug is wet

First of all, it is necessary to remove the muffler and carefully inspect the piston, since this is where the problem may be hidden. but the chainsaw still does not start or stalls, the saw does not start, Partner 350. In addition, most owners wonder: why does the chainsaw start and stall, while there are supposedly no problems with the spark plugs?

But this is an erroneous opinion and you don’t need to be so sure in this case, as there are situations when the candle sparks perfectly in air, but does not work directly in the cylinder.

The reason for this may be a direct violation of a kind of compaction in the canal area (impulsive). Or so there is a peculiar development of crankshaft oil seals, but this feature occurs in very rare cases.

The Shtil ms 660 chainsaw is the most economical of the entire Shtil chainsaw line. Its price ranges from 3,100 to 5,500 rubles.

Plant structure

The first and practically main element of a chainsaw is the engine, namely a two-stroke carburetor (see carburetor adjustment). Its direct power can be varied, it all depends on the model of the device and its intended purpose.

headset (saw) which consists of a chain (cutting), bar, sprocket, wheel (chain)

It is important that it always needs to be directly selected from the specific characteristics of the engine. Why does the Stihl 180 chainsaw not start, and why does the saw not stall? Since the larger the pitch of this type of headset, the deeper the chainsaw’s cut will be, one might even say that the more powerful and productive it will be. But do not forget that for the device to fully operate, the engine should also not be inferior to it in terms of power.

Its lubrication is carried out using special oil directly from the second tank, which is located on the hand unit. It is worth noting that the mass of this type of tank has such features that the oil and fuel intended for the engine run out at the same time.

We have figured out the general outline of the device, and most likely its basis, and now it’s time to start understanding why the chainsaw stopped working, what the reasons could be for this and how to eliminate them.

Briefly about the main thing

This model is the pride of the German manufacturer and is a direct tool intended for minor work. It can be used for no more than twenty hours per month. This wonderful device will easily help you take care of your garden, prepare firewood for the winter (see how to cut down a tree), clear areas, and will also be an indispensable assistant in other areas of, let’s say, simple manipulations.

And the world-famous company Stihl produces a huge range of high-quality chainsaws. For domestic purposes and simple work, the Shtil 180 chainsaw was created, which showed excellent performance and reliability. All the best practices of the German company were used here; with a weight of 3.9 kg, the chainsaw easily performed work in the garden. It is easy to trim small trees, branches, and you can even prepare firewood. But even the highest quality equipment tends to break down, and it happens that the Shtil 180 chainsaw does not start or starts with great difficulty. We tried to collect all the reasons and methods for repairing the German Stihl 180.
