How to adjust the carburetor on a chainsaw

A chainsaw is a modern tool used to perform various repair and construction work.

Like many modern tools, a chainsaw requires timely and high-quality maintenance.

As a rule, for high-quality operation, you need to adjust the carburetor of the chainsaw.

The carburetor is one of the most significant elements of a chainsaw, which supplies fuel to the engine of the tool. The quality of the carburetor directly affects the power and efficiency of the unit, as well as its economy.

To be fair, it should be noted that the carburetor needs to be adjusted infrequently.

This is because the factory settings of the chainsaw carburetor are optimal for high-quality work. If necessary, experts recommend repeating, more precise adjustment of the carburetor by rotating the adjusting screws. It is necessary to adjust the carburetor of a chainsaw when the adjusting screws become loose.

In this article we will help you understand in more detail how to set up a carburetor on a chainsaw.

A little theory

It is important to know that there are certain signs that indicate that the chainsaw carburetor requires adjustment. The following signs exist:

The following signs exist:

• Poor motor performance

The engine at this moment is difficult to start and constantly stalls and stops starting. This is due to the use of low-quality fuel.

• Excessive fuel consumption

. that is, consumption is above normal. The exhaust is black because the fuel is not completely consumed. The reason for this phenomenon is a supersaturated fuel-oxygen mixture.

• One of the rarest failures can be considered a broken fastening of the adjusting screws

This is due to the protective cap, whose coating is not entirely intact.

• Severe piston wear

. This requires mandatory repairs, which adjustment will only delay.

• Carburetor clogged

. associated with the consumption of poor fuel. In this case, both adjustment and flushing of the carburetor is carried out.

If you decide to repair a chainsaw carburetor with your own hands, then it is important to first learn to distinguish its three screws. Each screw has its own function and is designated by a Latin letter

Each screw has its own function and is designated by a Latin letter.

L – is responsible for the mixture, its quality at low speeds of the chainsaw

H – responsible for the quality of the mixture at high speeds

T – regulates the quality of the mixture at idle.

It is also important to read the instructions supplied with the device by the manufacturer.

Carburetor adjustment

To adjust the carburetor, you need to check the initial settings of the screws.

This is done with a thin screwdriver. Then you should check the filters and their cleanliness, as well as the mufflers. It is also necessary to check the fuel poured into the carburetor.

The next step is to warm up the chainsaw to the desired temperature.

Next comes the most difficult part - setting the maximum idle speed.

Next, screw “L” is unscrewed a quarter turn.

If the chain rotates, you can also remove the "T" screw. After the work has been done, you need to set the maximum speed using the “H” screw.

This can be done by screwing this screw all the way, which will cause engine malfunctions. After this, you should tighten the screws back.

Next, turning the “T” screw, we achieve low speeds by unscrewing it so that the chain stops. In this case, the speed should be idle.

After the completed manipulations, the correct adjustment of the screws, the correct operation of the carburetor are checked, and the power of the chainsaw is assessed.

With proper adjustment, the speed increases steadily. This happens even when you lightly press the trigger lever.

If you cannot adjust the carburetor yourself, you should contact a specialist, because an adjustment done incorrectly can damage the engine.

Setting up the carburetor on a chainsaw

To adjust the carburetor of the chainsaw, you then need to use the tachometer, that is, in general it works and develops power and it seems you can work. After such settings, you need to cut something. To check operation at high speeds.

Carburetor diagram: 1 – fuel supply fitting; 2 – channel for supplying air pulses to the fuel pump membrane; 3 – fuel inlet valve; fuel pump (diaphragm); 5 – valve for releasing fuel from the fuel pump; 6 – filter element for the fuel mixture; 7 – air damper, which is closed when starting and warming up the engine; 8 – main throttle valve, which regulates the engine operating mode and its power performance; 9 – fuel supply channel for mixture formation; 10 – idle speed adjusting screw (ISR); 11 – needle in the fuel supply system; 12 – idle jet; 13 – membrane; 14 – fuel accumulation chamber in the carburetor; 15 – carburetor main jet; 16 – diffuser, the main evaporation of fuel occurs here; 17 – screw for adjusting the fuel supply through the main jet.

What should you pay attention to when working?

First of all, to enrich the mixture, you can see this in the exhaust

When we unscrew screw H or screw L counterclockwise, we pay attention to the exhaust system. If during work we start to see blue smoke coming from here, it means we made the mixture too rich

It will lead to carbon deposits on the rings and carbon deposits on the candle.

If we have an exhaust with a very strong crackling sound, it means we have detonation, a lean mixture. A mixture that is too lean can lead to engine overheating and, accordingly, to burnout of the pistons, cylinder wear and spark plug burnout.

This is why a tachometer is used to set the minimum idle speed and maximum idle speed.

Which tachometers to choose

As for tachometers. There are tachometers produced by STIH, ECHO are quite expensive, and very good tachometers. And there are no extra wires that need to be connected to the device. The tachometer is simply applied to the saw and counts the revolutions. It’s a good thing, but expensive. There are Chinese analogues. Since the PIT saw is Chinese, the tachometer can also be purchased from China. The tachometer is connected to the high-voltage wire, using the wire from the tachometer, it is simply wound around it. We turn on the device and set up.

What kind of damage may occur?

Chainsaw malfunctions can be divided into groups:

• Engine malfunctions (ignition, exhaust and cylinder-piston systems, fuel supply).
• Failure of components such as the clutch, chain brake, lubrication system or tire.

Chainsaw engine failure is more common than others. Most of the time is spent on its detection and repair. As a rule, it comes down to such manifestations when the engine runs unstably or stalls altogether, the engine does not start, and does not develop power.

Before you start repairing your chainsaw, first check all the possible causes of problems in its functioning, or better yet, watch the video. Fortunately, today you can find any material of interest on the Internet.

Then you will have to prepare the necessary tools to repair the damage:

• device diagram (must be included in the delivery kit);
• keys, including spark plugs.

Self-adjustment of the carburetor Partner 350

When starting to adjust the Partner 350 chainsaw, you need to clean it as much as possible from dirt and dust in the carburetor area.

First stage of adjustment

The Partner 350 has special holes on the left side of the top cover through which you can access the adjustment screws, but if you are adjusting the chainsaw for the first time, it is better to remove the cover. This will be more convenient, because you will see in what position the heads of the adjusting screws are located.

Next, you need to set the quality and quantity screws to the fully tightened position, and then loosen them 1/5 of a turn.

If you adjust with the cover removed, then you need to remember that the left screw is the quantity screw, and the right screw is the quality screw. To make it easier, the manufacturer puts markings (L) and (H) on the carburetor body, under each of the screws. (L) – quantities. In some manuals it is also called a screw, which is responsible for traction at low and medium speeds. (H) – fuel quality, regulates the number of maximum revolutions.

Also, there is a third adjustment screw on the carburetor, which is designated by the letter (T). It is necessary to adjust the throttle position in idle mode.

Tip: If for some reason the carburetor does not have markings on the adjusting screws, you can identify the screw (T) by the spring installed on it, which is necessary to prevent spontaneous unwinding during operation. It also has a head for a Phillips screwdriver.

Second phase

After the screws are installed in the required position, the Partner 350 chainsaw must be started and allowed to run for several minutes, since the adjustment must be carried out on a hot engine. As soon as the cylinder becomes warm, you can begin to adjust the quantity screw; to do this, you need to tighten it clockwise until the engine produces maximum speed, then immediately unscrew the screw in the opposite direction by one quarter of a turn.

In this position of the screw (L), the chainsaw should operate confidently at idle. If there is a lot or too little idle, then they are adjusted using the throttle position screw (T).

Next, using the quality screw, the maximum speed is set.

Important: it is worth remembering that correct adjustment of the maximum engine speed is possible only with a tachometer. You can only determine the number of revolutions by ear approximately

Exceeding the maximum engine speed will inevitably lead to scuffing of the CPG and premature destruction of the crankshaft and connecting rod bearings.

According to the technical characteristics of the Partner 350, it can be set to a maximum of 12,500 rpm.

Adjustment without tachometer

When adjusting the carburetor without a tachometer, you need to focus on the sound of the chainsaw and its exhaust. If the saw smokes heavily, this is a sign of improper adjustment. To eliminate this, you need to slightly tighten the quantity screw (L). If the chainsaw does not pick up maximum speed well, but works well at idle, then you need to slowly tighten the screw (H) while fully pressing the gas until the saw starts working easily.

The video below provides instructions on how to independently adjust the carburetor of the Partner 350 saw without using a tachometer. This video does not show a professional master, but an ordinary user who, using the correct algorithm, adjusted his chainsaw with high quality.

Purpose of P360S

Chainsaw Partner 360 is a household model of a gasoline chain saw. According to the manufacturer's recommendations, it can be used for work in a summer cottage. For example, you can use it:

• prepare firewood for heating;
• trim tree branches;
• sawing boards during self-construction;
• do figurative wood carving.

Thanks to additional attachments, which are sold separately, you can significantly expand the functionality of this chainsaw and use it as a motor drill, mower or motor pump for pumping liquids.

If you are interested in expanding the functionality of the Partner P360S chainsaw, you can read more about them on our website in the article Attachments and accessories for chainsaws.

Below is a video about the Partner P360S chainsaw. The author talks in detail about this saw, its technical characteristics, and at the same time unpacks it and prepares it for work.

Basic faults

Like all push-pull saws, the Partner p340s has problems that can be easily fixed without contacting a service center. These disadvantages include:

• No idle speed (one solution to the problem is adjusting the carburetor);
• Difficult start (in some cases also solved by tuning);
• There is no spark (to fix it, you need to replace the spark plug, check and, if necessary, install a new ignition coil, it is also called a magneto);
• Clutch malfunctions (resolved by replacing the assembly).

Most chainsaw problems are caused by improper use. It is also necessary to monitor the condition of the saw and carry out timely cleaning and maintenance.

Never leave filled Partners p340 for a long time. Before downtime that will last more than a week, be sure to drain the fuel and use it to “burn out.” How to do this is described in the operating instructions provided by all Partner saws and more.

To solve more complex problems, such as loss of power from the tool or the inability to start the saw, you will need to contact a service center or perform a full diagnosis and repair of the Partner p340s. To familiarize yourself with the repair process, we recommend watching the video on how to diagnose, diagnose and repair your Partner p340.

Assembly Partner 350

In order to correctly assemble Partner 350, it is necessary to install all elements in the reverse order of removal.

An important feature of the Partner 350 chainsaw engine assembly is that the crankcase cover is installed without a gasket. Instead, a red sealant is used, which is applied in a thin layer to the crankcase installation site.

Before applying the sealant, it is necessary to degrease the crankcase cover and its installation location for better adhesion of the sealant.

Setting the flywheel and coil clearance (ignition adjustment)

During the assembly process of the Partner 350 chainsaw, if not only the flywheel, but also the ignition coil was removed, a gap must be set between them. To do this, first install the flywheel, then place a piece of a one and a half liter plastic bottle on it, and then place the coil and fix it with two fastening screws, while the flywheel must be turned toward the coil with magnetic contacts.

After adjusting the clearance, rotate the flywheel. If it does not touch the coil contacts, then the gap is set correctly.

Carburetor adjustment

The Partner 340 has a Walbro adjustable diaphragm carburetor.

To set yourself up, you'll need a special screwdriver and a tachometer (a device for checking engine speed).

READ Carburetor Adjustment for Chainsaw MS 660

The adjustment screws are defined as standard. Screw (T). Adjusts the idle speed. (L). Responsible for the quality of the fuel mixture at low and medium speeds. (H). Regulates power and high speed.

If you do not know how and why the adjustment is made, it is better to contact a service center. Otherwise, you risk damaging the engine by setting the wrong settings.

The carburetor of the Partner 340s chainsaw is adjusted in two stages. The first stage of adjustment is carried out with the saw muted. To do this, set screws (L) and (H) to 1.5. 2 turns from fully twisted. Screw (T) is half tightened.

In the second stage, the chainsaw is started and allowed to run for a few minutes to warm up. Next, using the tachometer, they find the position of the screw (L) at which the engine will idle at maximum speed, and turn the screw ¼ back, turning it. Idle speed at idle is normal. 800 rpm is considered normal, you can check the tachometer. If there is no tachometer, you need to set the number of revolutions at which the dust chain does not spin at idle, but the chainsaw operates stably.

Screw (N) sets maximum speed. For p340s Partners their cost is 13,000.

DIY chainsaw carburetor repair Partner 350

The carburetor parts of the Partner 350 chainsaw do not experience strong mechanical and thermal loads during operation, unlike, for example, a piston system. Therefore, in theory, there is nothing to break in it. In practice, after many years of operation, gaskets most often depressurize and the elastic membrane fails. Over time it can become tough.

In addition to breakdowns, the carburetor of the Partner 350 chainsaw may fail due to contamination. For repairs and cleaning, the carburetor is removed and disassembled.

How to remove and disassemble: step-by-step algorithm

Before removing, the carburetor of the Partner 350 chainsaw and the space around it must be cleaned with a brush so that dirt does not get inside the engine. After which they remove:

• Air filter.
• Fuel hose.
• Throttle linkage.
• Then the screws securing the carburetor to the engine body are unscrewed.

After removal, place the carburetor on a clean surface and unscrew the screws securing the cover to the body. Remove the cover and gasket. Parts and fasteners are laid out sequentially. Disassembly is carried out slowly, remembering well which part was removed from where

It is extremely important not to confuse screws H and L when assembling. They are the same in shape, but different lengths

After the operations have been completed, the Partner 350 carburetor is available for cleaning.

Cleaning the carburetor: basic points, how to clean it correctly

Whether the carburetor is clean or not is usually determined immediately, visually.

First of all, the smallest holes become contaminated - in the nozzle, diffuser, channels. There may be dirty sludge in the chambers. The disassembled carburetor body and parts are washed in a bath of gasoline or kerosene. Then the channels and holes are blown out with a car pump or air compressor. It is best to use a special nozzle with a thin channel at the end. Wash again.

During assembly, if necessary, replace the gaskets and membrane with new ones from the repair kit.

Repair kit: what is included in it and where to buy

Repair kits are sold with two sets of configurations.

The first includes gaskets and a membrane, that is, non-metallic spare parts. The second one additionally comes with a crosspiece with a needle valve.

Operating instructions for chainsaw Partner 351

Chainsaw Partner 351 differs little from other saws of the same class. Before working with the tool, it is necessary to install all removable parts in place and adjust the chain tension. The saw set, with the exception of the sprocket, is lubricated automatically, so it is also necessary to fill it with fuel mixture and lubricant.

Start the saw from a position on the ground, securing the tool with the foot threaded through the rear handle. Start the starter with the flap extended. Then turn on the ignition start button and press the primer 6 times and then proceed to restart the starter. After starting, let the tool run idle for a few seconds and use the throttle to adjust the power for operation. After which the operator proceeds to sawing with a Partner 351 chainsaw.

Conclusion

Knowing how much a carburetor for a Partner 350 chainsaw costs, any owner of this saw, before completely replacing the unit, tries to repair and adjust it himself. Often such repairs lead to the complete destruction of the carburetor, and in the case of adjustment, the death of the engine. In order to avoid such problems, you need to familiarize yourself with the repair and adjustment process in advance, but the best option is to entrust the repair and adjustment of the Partner 350 chainsaw carburetor to professionals.

Chainsaw Partner P340S – tool design

The standard equipment of this amateur model includes everything necessary for continuous comfortable work on the site. The engine of the gas-powered tool is 1-cylinder, running on a fuel mixture of 92 gasoline and oil for lubricating 2-stroke engines. A proprietary Japanese Walbro carburetor, the walls of which are covered with a continuous layer of protective chrome alloy, is responsible for the continuous enrichment of fuel with oxygen and its supply to the cylinder.

To ignite the fuel in the engine cylinder, the ignition system, which consists of a coil and a spark plug located above the engine, is responsible. The principle of starting the engine is manual. For this purpose, the Partner chainsaw is equipped with a starter and a pump for pumping fuel into the cylinder before starting a cold internal combustion engine. A separate cover, which is secured with several screws, is responsible for protecting the spring and starter coil on the left side of the chainsaw.

For continuous connection between the motor and the saw set, the Partner chainsaw is equipped with a reinforced clutch, all parts of which are made of hardened steel. This material allows the mechanism to operate under higher loads without the risk of blue clutch cams.

To protect all the internal components of the chainsaw, the manufacturer equipped it with a durable casing made of several layers of sheet plastic. At the back of the case there are switches and a power button for the model. The chain inertia brake lever is located in the middle, and the handle and starter cable are on the left side of the housing.
