Stihl 180 Doesn't Start When Hot Reasons

Supplying fuel to the chainsaw

If the Stihl 180 does not start and a spark occurs, then first of all we check the presence of fuel in the chainsaw tank. Of course, the problem is funny, but quite common. Next, we check whether fuel enters the carburetor; To do this, you can disconnect the gasoline hose from the carburetor and pump gasoline. After several manipulations, gasoline should flow out of the hose, but not in a large flow, but in small jerks. If gasoline does not work or does not work well, the problem may be the following:

Clogged fuel supply channel;

Directly connect the fuel filter.

As much as it sounds, even a too full fuel tank can cause this. If the pressure is high, the fuel hose may become loose or fail to create the required vacuum. Be sure to monitor the quality of the fuel used; To ensure proper operation, never leave your chainsaw running on gasoline for more than 2 weeks. Long-term storage of fuel in the tank promotes the formation of resins and the polymerization process of components.

Checking the fuel system

First you need to check the condition of the fuel filter. To remove it, you need to unscrew the fuel tank cap. Next, aluminum wire with a bent end will come to the rescue. With its help, remove the fuel hose, at the end of which there is a filter.

The condition of the filter can be checked by blowing into it. If air does not pass through, then the filter needs to be cleaned or replaced. If air flows freely, you need to look for a blockage in the fuel hose by disconnecting it from the carburetor. The blockage can be cleared mechanically or by replacing the hose.

If the fuel hose and filter are clean, but fuel does not flow to the spark plug, the cause may be a malfunction in the air pulse supply to the fuel pump.

Chainsaw Stihl 180 does not start: causes and repairs

No spark

If your chainsaw won't start and you haven't had any problems before, the first thing to do is check the spark plug. A spark may simply not occur between its electrodes; this can only be determined after removing the spark plug. We check its performance by placing the spark plug against the cap of the high-voltage wire and placing the spark plug on the metal side of the cylinder (or other metal object). Now we are doing several manipulations of the starter, and if during them there is no spark, the problem lies precisely in the spark plugs.

Attention: you must make sure that the inflammation is turned on, otherwise the spark plug will never show a spark. Also, to make sure it is the plug that is faulty and not the ignition coil, take a similar plug and test a spark on it. If there is one, the problem can be solved by simple replacement.

Faulty crankshaft bearings

If your Stihl 180 won't start and the fuel is flowing properly, you'll have to look further afield, namely the crankshaft. Its bearings tend to wear out, causing play and attempts to wobble the flywheel. The fact is that when there is a game, the flywheel magnets are attracted to the ignition coil, or rather to its contacts.

To repair and replace bearings, you need to disassemble the motor, so this work is performed only by craftsmen or people who have experience. Do not disassemble the engine if this is your first time.

Floods the spark plug

In some cases Stihl

The 180 will start and stop or not start at all. Then we check the condition of the candle; it can be refilled. The reasons for this overflow can be two incorrect cold starts, engine and carburetor malfunction. We are trying to solve the problem by doing the following:

Remove the spark plug;

We turn the chainsaw over to the other side and wait until the excess fuel is gone;

For better confidence, we pull the starter several times, so the gasoline will definitely come out of the cylinder

We return the spark plug to its place, install the cap and try to start the engine again with the starter.

When is a piston replacement necessary?

The circumstances for which the piston needs to be changed, in general, and one hundred percent of the piston, you will like enough, alas, what remains to be done by our client, they are divided into natural and those that appeared during incorrect operation. Natural, this is wear and tear formed due to long-term use of the Shtil 180 chainsaw. Artificial ones are not easy, for example:

overheating of the motor and the occurrence of thermal seizures;

entry of a foreign body into the cylinder and the occurrence of mechanical scuffing;
piston ring breakage due to exceeding the highest engine speed;
piston skirt failure due to overspeed;
the introduction of bad fuel, under the influence of which the piston group of the chainsaw wears out the unfamiliar intake channel in the cylinder;
operating a Calm chainsaw with a dirty fuel filter, which reduces the percentage of oil in the fuel consistency;

It is necessary to diagnose the CPG in this case if the Shtil ms 180 has sharply lost power, or in other words, does not start, in this case the starter of the tool does not turn. For which the design is intended, if the starter turns, alas, the saw does not start, while of course the spark and fuel enter the cylinder properly, you need to measure the compression in the engine.

If you suspect difficulties with the CPG, it is better to contact a service center authorized by the manufacturer, since it can only accurately diagnose the malfunction without a complete disassembly and, if necessary, carry out high-quality repairs.

Other reasons and solutions

If the chainsaw still does not start and the reason is not in the details listed above, you need to look deeper. Other common problems include:

Fuel pump failure;

Lack of impulse in the pipe channel from the engine crankcase;

From the carburetor to the forum fuel supply;

Diaphragm rupture on the fuel pump;

The above-mentioned malfunctions can be corrected either independently, but it is usually better to give the chainsaw to a specialist; you can make a diagnosis yourself. When diagnosing, you should also check the following indicators:

Correct operation of the carburetor;

Optimal compression in the cylinder;

Compression in the crankcase.

Compression is checked both using a special device and manually. To make sure that compression occurs, simply remove the plug and insert your finger into the cylinder hole. After a few times, turn the starter and if the finger is pulled into the hole, compression occurs.

If the chainsaw starts and lags when you press the gas, this indicates poor fuel consumption. The cause may be a clogged fuel filter or carburetor jet. The first unit can be checked and cleaned very quickly, but in the second case it is better to trust the specialists.

Disassembling and cleaning a chainsaw carburetor requires experience and care. Therefore, only those owners who have already repeatedly and successfully completed this procedure are usually accepted.

The air filter should also be given attention so as not to look for the cause of the chainsaw malfunction in the wrong direction. If it is clogged with dust, then you cannot count on easy starting and stable operation.

This valve equalizes the pressure in the gas tank as fuel is consumed. When it becomes clogged, a vacuum forms in the tank and fuel stops flowing to the carburetor. This disease is treated by cleaning the breathing tube with a regular sewing needle.

It is easy to remove dihalnik from the list of suspects. To do this, disconnect the fuel hose from the carburetor and see if it smokes fuel. When gasoline flows in full, the fan is clean, if fuel does not come from the gas line or it flows out very slowly, then the reason

fault is established.

Stihl chainsaws are intimidated by the increase in idle speed after the first tanks of gas are used. Experts consider this behavior of the saw to be normal and indicates that the engine and carburetor are working properly. Therefore, do not rush to contact the service, but only slightly reduce the engine speed using the carburetor idle screw.

No fuel supply

This type of malfunction, like others, has its own characteristic symptom. It lies in the fact that the working spark plug, which holds the spark, will be completely dry. You can check for suspected lack of fuel supply using the following algorithm.

The main causes of such malfunctions are the carburetor and filter, which may simply be clogged.

In order to exclude the interior from damaged objects, it is necessary, first of all, to disconnect the fuel hose from the carburetor itself and actually check that fuel is not leaking from it.

You must remember that in the process of proper operation of the chainsaw, gasoline must flow out in a dense and stable stream. In addition, it is not uncommon for a Stihl 180 chainsaw to not start hot and barely linger after being turned on or hold power for a fairly short time. In this case, the problem of breakdown lies precisely in the muffler, which may simply be clogged. With any deposits that arise during the operation of the device and which settle during the exhaust process.
Also a fairly common cause of tool malfunction is insufficient lubrication of the device chain itself. The reason for this may be channels that are simply clogged, or a reason
. In an oil pipe that is leaking.

Chainsaw chain lubrication

Pipe connections or connections in the area of the oil pump fittings may also leak.
It happens that the Stihl 180 chainsaw does not start well through the cylinder, which can be cracked. But to determine its condition, a visual inspection is sufficient. But even if you find irregularities and chips there, you can be sure that you have found the cause of the breakdown.
If, after checking, you find that the spark plug is faulty, then you just need to turn it off and then dry it directly. But it is worth noting that under no circumstances should you pierce it, as you will simply ruin the part and it will be unusable. You also need to drain excess fuel from it through a special hole.

In addition, you must remember that direct drying should be carried out for at least thirty minutes, and only after this kind of manipulation can you install it back and actually try to run the tool directly.

Moreover, it may happen that your candle has simply passed its expiration date, in which case it needs to be replaced. Therefore, it is excellent advice that it is better to always have a new candle or, better yet, a set. Then you can replace it at any time and actually understand whether this was the direct cause of the device failure. Moreover, a weak contact that actually connects the high-voltage wire and the end of the spark plug can also cause failure. A faulty ignition unit may also be the cause. It is worth noting the fact that to eliminate such problems it is necessary to replace the unit itself, since it cannot be repaired.

No less important is the concern of the owners of this model regarding the systematic idling after the first gasoline tanks are emptied. But if experts in the field are to be believed, they claim that this situation does not pose any problem. But still, if a similar process is repeated quite often, then you just need to reduce the engine speed using the carburetor screw.
In addition, you can clean the muffler yourself, since the cause of
the malfunction. This manipulation is not difficult. A fairly common occurrence of poor-quality tool performance is the carburetor.

But it is worth noting that it will be better if specialists are involved in its repair, because if you have the necessary knowledge and skills, then you can simply break it and buy a new one.

It is important that even if you have discovered the very cause of the device malfunction, this does not mean that you can fix it yourself. Because there are some breakdowns that only a specialist can fix. If you have carried out direct manipulations to check and change the quality of the oil (see Oil for Stihl chainsaw), but, nevertheless, the chainsaw still refuses to start, in this case you need to continue the search.

But if you have completely completed all the manipulations described above and have not missed a single nuance, but still the tool has not yet been fixed, then the problem lies in the group called the cylinder. But if you still couldn’t bring your iron friend back to life, then just take the chainsaw to a service center, where the device will be repaired for you.

How to check the receipt of an impulse from the engine crankcase

The fuel pump is located in the carburetor. Its operation is carried out by the receipt of impulses from the engine crankcase through the impulse channel. The channel is located in a rubber pipe through which the cylinder and carburetor communicate.

If the pulse channel becomes clogged, the quality of the fuel supply decreases or it does not arrive at all. To gain access to the pipe, you need to remove the air filter housing and carburetor. After this, the channel is checked or cleaned using a metal wire.

Adjusting the idle speed of the Shtil 180 chainsaw carburetor

The design of the Shtil 180 chainsaw contains many rubber parts. All of them require systematic inspection for cracks and other defects. If they are present, the parts are replaced with new ones.

Another reason for the lack of impulse may be depressurization of the Shtil chainsaw engine crankcase. In this case, the air supply to the pump is reduced or completely stopped.

Check the tightness using a vacuum gauge. If it is absent, a medical syringe will come to the rescue. The operation is carried out on an engine with the carburetor removed. Take a little motor oil into the syringe and pour it into the impulse channel, and then pull the starter handle.

If there is no pulse, the oil will remain in the channel. This problem can be resolved by disassembling the engine and replacing the seals. If the oil is squeezed out of the channel, the problem probably lies in a pump malfunction.

Stihl 180 Starts Poorly When Hot Reasons

Stihl 180 chainsaw Reasons and solutions!

Today the manufacturer Stihl

occupies a leading position among other companies producing equipment for agricultural and construction work. The products of this manufacturer are famous not only for their high level of quality, but also for their optimal pricing policy and the power of their models.

It is probably quite difficult to meet a person who does not have a chainsaw of this brand. This is one of the world's most famous companies. But the fact is that out of ten possible six people there definitely are. This is not surprising, since Stihl chainsaws provide power as well as sophisticated design. But, unfortunately, such technology giants sometimes break down and require some repairs. Today we will pay attention to one of the moths of this manufacturer, namely the Stihl

ms 180. Read about
the stihl
ms 660 chainsaw here. So, let's begin.

Conclusion

If the Shtil MC 180 chainsaw stalls at idle, does not gain power when you press the gas, or even stalls at full speed, it is necessary to diagnose the fuel system and check the crankcase for leaks. You can do this yourself, but you need to have certain skills. If you are not very familiar with push-pull saws, it is better to turn to specialists, since this technique is quite capricious and any mistakes are expensive.

For what reasons does the Stihl MS 180 chainsaw not start?

Chainsaw Stihl

MS 180 is considered one of the most reliable tools used in gardening. But with any technology there are situations when for some reason it does not start. Let's look at the main problems that can cause your Stihl 180 to not start or start poorly, and how to fix these problems.

Winding device

The basis of this type of model, like all other chainsaws, is the carburetor. But since we are talking about the Stihl 180 chainsaw today, we will not go off topic. Yes. The carburetor in this model has a single tuning screw, that is, it is a kind of idle speed adjustment screw. While the jet is fully loaded, it is motionless.

Chainsaw carburetor Stihl 180

In simple terms, we can say that it simply cannot be adjusted (see here), whereas the full load setting simply cannot be changed. It is important that the carburetor itself is configured at the factory in such a way that, regardless of the actual conditions under which the chainsaw directly operates, the air-fuel mixture is supplied to the engine itself.

READ Stihl Chainsaw How to Remove Cylinder

Spark plug faulty

The first thing you need to do is check the performance of the spark plug.

This is quite easy to do. The spark plug is inserted into the high-voltage wire cap and pressed against the engine cylinder, after which the starter moves several times, if there is no spark between the electrodes of the spark plug, it is faulty or the ignition module is faulty.

In order to know for sure that the problem is with the spark plug, you need to check a known good one in the same way. If a spark appears as a result of the test, then the problem has been detected, and to eliminate the problem we replace the spark plug with a new one.

Overheat

Overheating of the motor during operation may cause the saw to stall and not start. Overheating is quite dangerous, as it can cause the piston in the cylinder to melt and the engine to seize up. At the first cases of overheating, it is worth diagnosing the tool for the presence of foreign air being sucked into the engine and adjusting the carburetor.

Air leakage, as well as improper carburetor adjustment, affect the maximum number of engine speeds and its lubrication, which, in turn, causes overheating and clogging of the tool.

Spark plug

The spark plug is one of the main elements of the ignition system. A spark is generated across its electrodes, and if this element fails, it will be difficult to start, or even impossible to start.

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 cover of the high-voltage wire and, placing it on the cylinder, pull out 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 indicates a problem. A faulty plug must be replaced.

Problems in the fuel system

If during inspection it was determined that there is a spark and the plug is dry, then there are problems in the fuel system. Checking it should start with the fuel filter. Next, you need to inspect the fuel hose and its attachment to the carburetor, pay attention to fuel leakage from the carburetor and the presence of gasoline in the air filter housing. It is advisable to start removing the carburetor only if a visual inspection does not allow us to determine the cause of the breakdown.

A common symptom of a problem in the fuel system. Excess fuel in the engine cylinder. As a rule, this is indicated by excessively wet spark plugs and the presence of a spark at the plug contacts. In this situation, it is necessary to turn the chainsaw over so that the hole in the plug is directed downward. If gasoline flows from the cylinder at the same time, then the reason that the chainsaw does not start is fuel overflow into the engine.

The carburetor adjustment process can be found on the Champion 254 saw by looking at the instructions.

Carburetor repair overview

Review: the chainsaw starts and stalls. Reverse air leak into the tank

Review: won’t start, starts and stalls: how to fix?

Ivan Samoilov, 38 years old, Amur region

“My Chinese saw doesn’t start well; in general, we can say that it doesn’t start, because it immediately stalls. I start it up through rather complex manipulations, at full throttle it works and saws for some time. However, after a short time it begins to sneeze and stalls - it is impossible to work. I tinkered with it myself for a long time, and then took it to the workshop. It turned out the magneto came off - I never would have thought it was the fault of the carburetor.”

Ivan Vesnin, 33 years old, Solnechnogorsk district

“After winter I decided to take my chainsaw for a walk in the garden. Right away everything went well, I managed to start it up quite quickly, after warming up I even trimmed one apple tree, and then it began to stall. It will run for 8-10 minutes and then die. And not only under load, but also at idle. I was already scared - I decided that it was time to change the piston.

Yakov Baulov, 59 years old, Siberian Federal District

“After a long period of inactivity (I didn’t approach it for the whole winter), the chainsaw began to stall at high speeds and when the gas was sharply applied. It seems to start gaining momentum, but when adding gas, at some point it stalls. It didn't start very well from the very beginning, but I adjusted the carburetor and it seemed to work out. In short, I searched for the fault for a very long time until I climbed into the gas tank and discovered that my chainsaw was not equipped with a fuel filter - there was simply the edge of the fuel line sticking out.

Why does a chainsaw have trouble starting?

Fuel and air filters;
Reduced compression;
Carburetor adjustments;
Spark plug;
Ignition coil;
Gap between ignition coil and flywheel;

Let's look at each reason in more detail.

Broken fuel wire

During operation of the chainsaw, vibration occurs, which can damage or break the chainsaw's fuel line. In this case, the chainsaw will stall and it will be impossible to start it. To diagnose a malfunction, you need to conduct an inspection and determine the presence of fuel leaks.

Chainsaw won't start

Every person who is familiar with gasoline tools knows that sometimes the equipment works intermittently, or it may freeze in an instant and will not start again. We will try to consider the most common reasons why a chainsaw does not start.

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.

Reduced compression

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

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

The reasons for the lack of compression or its decrease may be natural, as the engine wears out during operation. Problems can also be caused by serious damage, such as a beaten CPG or 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 completely CNG.

Starting without a starter

Often, many home craftsmen are interested in whether it is possible to power a chainsaw without the help of a starter. The answer is very simple: this cannot be done in principle. None of the manufacturers have provided other alternative starting methods. Therefore, even if you remove the starter and try to start the car in some other way, it still will not work, since disturbances will occur in the cooling system. This system contains a volute to transmit the flow of cold air from the flywheel impeller towards the cylinder. If it is not there, the engine will overheat and eventually seize.
