Factory adjustment of the Carburetor of the Stihl chainsaw.

Adjustment of the carburetor of the chainsaw STIHL 260

Stable sustainable work at any speed, developed capacity, efficiency, use of technical capabilities in the volume provided for and laid down by the manufacturer, and even a motorcycle resource. all this depends on its carburetor. In addition to the fact that this node must also be kept in the proper condition and served in a timely manner, it must still be correctly adjusted. Setting up the chainsaw carburetor is not easy, but with a unhurried thoughtful approach and clear following the instructions, it is feasible for almost anyone, and it should be carried out at the first signs of the need for this, and regardless of whether the new motorcycle is operated or the types of types is operated. The need to adjust the fuel supply unit (hereinafter referred to as the UPT, that is, the carburetor) is evidenced by the following reasons, signs and malfunctions:

  • factory or own settings were shot down due to weakening of adjusting bolts and vibration or in the process of unsuccessful attempts to adjust the carburetor in a new one;
  • damaged lid of the UPT case;
  • The engine does not start or starts with a strain, and then stalls almost immediately;
  • The saw does not work steadily at idle or does not keep them at all;
  • excess of fuel and too thick exhaust;
  • Electrodes of the spark plugs are black (supply to the re.enriched mixture motor) or with a white plaque (impaired);
  • Motopila does not develop maximum turns or power;
  • The motor stalls during a speed set;
  • strong vibration of the chainsaw is observed;
  • Due to violations in the operation of the air cleaning system into the distribution of the fuel-air mixture of the mechanism, particles of garbage hit;
  • The piston group has significant wear. in this case, the regulation of the UPT is used as a temporary measure that allows you to make the work of the tool more stable.

Naturally, when the mud gets into it, the fuel system needs to be washed. this problem cannot be solved by adjusting the carburetor. And a worn piston needs overhaul. However, in these cases, they also set up.

It can also be needed even when the brand or quality of fuel, atmospheric pressure, humidity and ambient temperature, height above sea level (when the place of operation changes from the plain to the mountainous terrain, and vice versa) can also be adjusted.

Before regulating the UPT, you must make sure that both filters (air and fuel) are clean. In addition, there should not be an air leak into the motor from the side (through the seals, laying under the UPT or its accelerating pump or somewhere else), otherwise it will not be possible to adjust the carburetor.

Almost any UPT is regulated by 3 screws:

  • one. The bolt of the chief nozzle designated “H” and used to set the maximum speed of the saw engine.
  • 2. Bolt of the idle jacket, designated “L” and used to set low speeds. That is, to regulate the idle.
  • 3. Idle taching bolt, indicated in various. “LA” (stihl), “t” (Partner, Husqvarna).

There are also carburetors with fewer adjusting screws. So manufacturers protect their products from unprofessional intervention and at the same time try to simplify their configuration.

Before starting adjustment, you should carefully study the operating instructions attached to the chainsaw, especially the part where the angles of rotation of the mood bolts are given. This is an important condition that will make it possible to set up without going beyond the operating parameters of the engine.

For safe regulation during its implementation, the rules should be followed:

  • one. The tool must be steadily installed on a flat surface of a rigidly fixed object (workbench, rack, table).
  • 2. The chain should be directed away from itself and other present.
  • 3. There should be a safe distance between the chain and any surrounding objects that guarantees the impossibility of their mutual contact.

In such cases, adjusting the carburetor on the chainsaw can be as follows. First start the tool and warm it up for 10 minutes.

We begin adjustment of the UPT by determining the position of the mood “L”, in which the idle speed will be the greatest. To do this, we very slowly and smoothly turn this bolt in one direction or the other. And so several times, until the right position is found. After that, we turn “l” by 1/8–1/4 turn (the required value is indicated in the technical documentation for the tool) counterclockwise (hereinafter PEF).

Then we continue to regulate the idle stroke using the screw “s” (“la”, “t”):

  • If the chain after manipulations with the bolt of “l” is motionless, then it is necessary to smoothly rotate “s” (“la”, “t”) clockwise (hereinafter referred to as it) until it starts to move. Then twist the “s” to 1/8–1/4 turns back.
  • If the chain moves, rotate “s” (“la”, “t”) of the PFS until it stops, and then twist “S” to 1/8–1/4 turns in the same direction.

The engine should work evenly. And check it, how it accelerates. It is believed that the engine in acceleration mode works normally if, when you smoothly press the accelerator, the revolutions in a short time and without “failures” increase to its maximum value. If the engine works unevenly and/or poorly accelerates, then it is necessary to slightly. a maximum of 1/8 of the whole turn. Turn the “l” PCH. After that, it is necessary to again make the above settings “S” (“LA”, “t”). Repeat these adjustments until the engine starts to work evenly and accelerate well.

Now check the setting of the adjusting bolt “H”. To do this, accelerate the engine to maximum speed. Only for a long time it is impossible to drive it so without load, you need to pause. We look at the exhaust and listen to the work of the motor. If too much comes out of the muffler, and the brutal smoke, and the motorcycle is very noisy, which means the carburetor makes an overly rich mixture. In addition, the maximum power of the power unit is lower than should be. And also in it will form. In this case, it is necessary to “h” a little to tinker. Then again check the operation of the engine and, if necessary, repeat the adjustment.

Probable malfunctions of the Stihl MS 211 chainsaw

Now, during the operation of the chainsaw, the Stihl MS 211 took and the staller. I poured the consistency (I follow the proportions correctly), began to start, did not start, dried a candle, cleaned, purged the engine as it is said in the operating annotation, the filter is unsuccessful. You started, you let go, it stalls idle here, so I worked a little with a gas.pressed gas and spat. After that, in general, I finished starting up, pulling, pulling, not even cotton, what is it, I won’t know. Can change the absorption in the gas tank? I have never changed it for the 2nd year, in the annotation, it is recommended to do this once a year, I don’t work much with a saw. No one has come across a similar unreasonable?

I had the same inconsistent did not start. Realizing that I myself would not do anything, I still went to the service center, all the more so that the guarantee has not yet passed. There, together with the master, we sorted out for a long time, inspected all the details, even put a new carburetor. All in any. There turned out to be a little trifle: the filter in the gas tank clogged. In some places bad gasoline came across.

I use this tool, everything would be nothing, but this is the problem. When filling the oil tank from 2/3 to the full level, it flows and perfectly, through the oil tank’s cabin, which is located in the tire attachment, ultimately leaks from under the tire very perfectly. The service manual shows how to remove the sapun out of the case, but how much I did not try and failed. Maybe someone to tell, how to do it, and what is the device of this sapun?

There is a ball valve in the case. But pulling them out of the buildings is quite problematic. He should only let in air. It is possible that something, the small one fell under the ball. In principle, I would recommend not yet touching the bacon, but simply not to leave the saw for storage with full tanks.

Model 211, jammed the driven chain star, what is the reason, what to do?

Most likely the reason is the needle of the chain wheel bearing, substitution is required.

STIHL MS 211 C-BE. Worked no more than 30 minutes. A couple of times clamped the tire, the chain stopped. And so, I drank stalled. He could not launch. The engine is very heated. For the next day he flooded the new fuel. Saw earned, but at idle, the chain continued to move. I decided to twist the idle (previously all the options were factory). LA twisted the screw until the chain stops, gave the gas. The saw stalled. Returned back the position of the screw la, started the saw. The chain moves, the saw does not stall. Again, adjust the idle. Everything is repeated, saw stalls. What could be?

Idle speed 2800, you cannot set the eye (hearing) if the chain moves at these turns. replacement springs of stretching clutch clutch. It costs inexpensively, work for 20 minutes in the service and idle adjustment. In general, if you give gas and saw it stalls like a clogged air filter. Another moment. 211 saw is very demanding on the quality of the fuel mixture. There should be a good gasoline, the correct mixture of 1/50 and it should not be old.

Read what kind of oil is poured into a chain electric saw

Tell me, in relation to the STIHL ms 211 saw. When buying, the seller of the official dealer, without filling chain oil into the tank, poured the fuel mixture into the saw, after which he started the saw and repaid for about 20 seconds. This is what all sellers do, or it would still be correct to fill the oil tank for lubricating the oil pump during trial launches (dry wear of the tire and chain excites less than the possible wear of the oil pump). After checking the fuel mixture, the seller leaked back to the captain of the seller. Is it now necessary to devastate the carburetor before downtime until the future of June? The seller said nothing. Start and drive at medium speeds or neglect gasoline in the carburetor? If you need to drive the saw until the carburetor is devastated, whether it is necessary to fill the chain oil into the tank?

Forgive what wear of the pump oil in 20 seconds, if then, when sawing there, few people look at or do not check the presence of oil when sawing. Initially, there is a lubricant on all surfaces. Before any long.term storage, it is necessary to drain and start, develop a mixture in a carburetor! Thus, you postpone the time when you need to contact the service to clean the fuel system.

With maximum speed and maximum load, the engine begins, as it were, to pass the speed, while it works stably, the thrust is very good. Maybe this is normal for the 2MIX motor?

The carburetor did not touch, the number of revolutions is normal? In general, engines with different technical solutions have their own “small” features in terms of launching, work, sound, etc. If it starts well, idle and workers are stable, the rod is normal, the oil is coming. what else is needed?

Tell. Piston for MS 211C chainsaws is compatible with any piston another brand of saw ?

The cylinder and piston group from MS211 is suitable only for MS-211 and MS211C.

One tank of oil for lubrication of the chain goes to two tanks of gasoline. Why is this happening, because the instructions written in the proportion of 1: 1?

factory, adjustment, carburetor, stihl, chainsaw

The oil filter was clogged, the oil was diluted not in accordance with the recommendations on the proportions for the season, most likely the oil is too thick.

Read adjusting the carburetor of the chainsaw STIHL MS

I took a used chainsaw STIHL 211. The chain is strongly worn out, you definitely should not sharpen it and I just can’t pull it. It seems to be pulling, I make a couple of revolutions behind the chain with my hand, and it sags again, a couple more revolutions and it pulls on, what is the problem can be? And how to remove the chain tensioner?

As for the sag of the chain, some “tightening after a broach” is permissible. This chain after the broach, as it were, finally becomes in place and is a little weakened, maybe from a too stretched chain, a developed star, defects of the tensioner mechanism. Drive the tensioner with the key and remove the mounting screw of the tensioner (it is closed by the bar, if it is still intact) and roll the tensioner with a screwdriver. Installation of the new in the reverse order.

STIHL 361 chainsaw areas

The Stihl 361 chainsaw is highly appreciated by professionals, although the average power level does not allow it to be used in specialized production. for example, on a pilram. But in construction, farm and garden farm, it has established itself as an excellent tool that works efficiently and stably.

Its advantages include: an increased level of security and convenience for the operator. Even heating the chainsaw handle for comfortable operation at low temperatures is provided.

This model is ideal for sawmills. STIHL MS 361 copes with a roll of trees of any complexity, their sawing, harvesting firewood, cutting branches and twigs. It is indispensable in construction work, especially in the construction of wooden structures. for the harvesting of a beam, figure processing of wood, etc. D.

An important advantage of the Stihl 361 chainsaw device is the ability to transform it into other useful tools. Using the desired set of nozzles, the chainsaw is easy to convert into a boat motor, a grinding machine or ice car.

Carburetor adjustment

If the Stihl 230 chainsaw starts up and stalls or just works unstable, then it is time to see how things are with the fuel supply system, namely the carburetor. Most likely the reason lies in it, and it requires maintenance. We will not dwell on this process within this article, t.to. Earlier they talked about the repair of the carburetor on the chainsaws in general and the STIHL in particular. We recommend reading articles: device and adjustment of the carburetor on the Stihl 180 chainsaw and the second interesting article about adjusting the carburetor on chainsaws in general.

The articles raise questions of the main reasons why the saw begins to “ruin”. Detailed and detailed answers are given that will help to repair the faults with your own hands.

If for some reason you cannot contact the STIHL specialized service, and you want to adjust the carburetor of the chainsaw with your own hands, then you definitely need to watch cognitive videos regarding this issue. We present to your attention, our selection.

Adjusting the carburetor at the STIHL 230 and 250 saws is no different, so watching the video will be useful to the owners of both the other chainsaws.

Carburetor Sthil MS180 (Stihl 180). Adjustment. no, I have not heard

On the chainsaws of the StiHL MS 180, the Chinese.made carburetors are installed now and in the past few years, which have only one adjustment screw. Such membrane carburetors are practically not subject to disassembly, since it is all overwhelmed and flooded. So to speak: “Adjustment. no, did not hear”In this case, it is easier to buy a carburetor of a chainsaw STIHL 180. over, there are carburetors on sale both original (also produced in the PRC, but at the factory belonging to STIHL), and from third.party (also Chinese) manufacturers.

It should be noted that despite Chinese production, the original STIHL 180 carburetors are very reliable and rarely summarize the owners then the original 2500, that is, almost 4 times more expensive.

For the released chainsaws for 5 years or more years, it is possible to purchase reprimatoes.

How to configure the carburetor of the chainsaw of Stihl 180?

Only idle adjustment is available to us. Why is it necessary and how to understand when you need to configure idle speeds not the Stihl 180 chainsaw? This is necessary if the chain does not stop at idle, which can lead to injuries, unstable operation of the saw in general.

The procedure for adjusting the STIHL MS 180 carburetor:

In the instructions for MS 180 it is described how to standardly configure idle on a chainsaw:

We turn the blanket of the idle speed against the sentry until it does not go tight, then we turn it off for two clockwork clockwork. Voila! Tun

If your saw has too low idle speeds, then we carry out the following actions:

If you have high speeds and the chain does not stop spinning:

�� Stihl MS 271 Maintenance and Cleaning, H & L carburetor adjustment 2021.

  • We turn the blanket adjustment screw counterclockwise until the chain stops moving.
  • We rotate the screw even on a hollow against the sentry.

If you fail to independently adjust the idle speed, you must contact a specialized service center.

Setting instructions

If there is a situation when the tool needs repairs for greater productivity and saving fuel, the carburetor adjustment with all related operations will be an indistinguishable event. Adjustment of the carburetor of the lawn mower 55, 250 and. And so, performing options for the carburetor system of saw 80, you need:

  • Clean the fuel tank and air filters, which will provide more high.quality actions.
  • Find the screws n, l and s on the carburetor.
  • Using the designated screws to produce the basic options of the mixer of the stihl 180 combustible mass, performed with the motor turned off: using the annotation, set clear angles of rotation of the screws n and l, which regulate the ratio of gasoline and air, where the screw N is the screw that controls the gikler of the highest revolutions; L is the screw of small revolutions; S. a screw of accuracy of idle values. When setting the basic values, slow down slowly H and L clockwise, after the stop, return to the position for 2 revolutions back.
  • Turn on the engine and perform the final setting with your own hands of the Stihl carburetor. Find the largest idle speeds, with a threshold of screw l in various directions. As the maximum will be found, the screw is returned 1/4 of the hours of hours. Optimal settings of the carburetor of the chainsaw of the carburetor MS 250 MS 660 P340S Partner. In the event of a chain, the idle screw is returned to its full stop.
  • Will perform the techno check and adjust the acceleration and the largest number of revolutions.

A chainsaw is a technically complex tool that must be served from time to time. Cleaning, replacing filters and of course adjusting the gasopyle carburetor, will help to last the entire time she has set for it. In this article we will consider the issue of setting a carburetor. How and for what it is carried out.

Each owner of the carburetor must have the necessary tools to adjust this system. There are three adjusting screws that are located on the device case. They have their own markings:

  • L. screw for correction of low speeds.
  • H. screw for adjusting high speeds.
  • T. regulates the idle speed, in most cases it is used for experiments.

Air filter of the chainsaw

Before adjusting the carburetor, you need to prepare the device:

  • The engine warms up, that is, it starts about 10 minutes before the repair, and turns off at the beginning of work (see. how to get a chainsaw).
  • Air filter is checked and washed.
  • The circuit stops by turning the screw t to the stop (see. Oil for the chain).

To carry out safe repair, you need to prepare an even surface, where you can carefully place the device, and turn the circuit in the opposite direction. Need a tachometer. It determines the presence of a violation in the carburetor. When revolutions, the sound should be perfect and absolutely even. If screaming notes are noticed, then the mixture is oversaturated.

Carburetor adjustment is divided into two main stages. The first is called basic. Correct adjustment of the carburetor of the chainsaw 180, 250, 260 and all models of the STIHL chain saw with your own hands. It is produced when the engine is turned on. The second is performed when the engine warms up.

To carry out the carburetor setup procedure successfully, you need to familiarize yourself with the instructions for the operation of a particular model in advance to identify additional features of configuring the device.

To correctly set the carburetor of the Chinese chainsaw, you must first remember the factory settings of the device, then turn on the engine. Later you will have to leave it to work for a few hours to accurately set its own parameters. Sometimes work is carried out once after the ten.minute functioning of the engine, however, many Chinese.made models require special treatment.

  • Events begin in idle mode. Using adjusting screws, you need to achieve a systematic set of revolutions with an engine, so you should first let it work at low speeds. Deviation from the norm is the movement of the chain by the bus. In this case, it is necessary to adjust the optimal position in extreme screws in order for the chain to remain motionless.
  • The transition to the momentum of medium speed is carried out. Sometimes the engine is smoking. This defect can be eliminated if you tighten the screw to serve a poorer fuel mixture.

In this case, the smoke will disappear, but the engine speed will increase. It is necessary to adjust the settings until the level is reached when, when pressing the throttle, the engine smoothly gains momentum, sharp jerks or interruptions are not heard.

  • The engine engine is being checked. The chainsaw is transferred to minimum turns, and then a rapid press is carried out on the lever. With maximum pressing, it is kept for 3 seconds. If there are violations in the operation of the engine, you need to gradually loosen the screw until the optimal position is reached.
  • The chainsaw should work for several hours in real conditions. It is necessary to engage in cutting wood, and then perform an inspection of all the elements involved in this event. If there are deviations, they need to be fixed using adjusting devices. When all defects are eliminated and optimal settings are set for the supply of correctly concentrated fuel, you can consider the process of configuring the device with complete.

Setting up a chainsaw carburetor. Or how not to pay repairmen!

The possession of a chainsaw in many ways makes life even lover, and in some professions this tool is actually indispensable. However, as any relatively complex device, chainsaws require periodic maintenance. Due to the untimely or not of the most high-quality maintenance, as well as as a result of the influence of both planned and excessive loads, various malfunctions may appear. For professionals, interruptions or unstable saw work reduces the efficiency of work or may cause a spoiled working day. One of the fairly common faults is the incorrect tuning of the carburetor of the chainsaw, which is lost due to unsuccessful attempts to adjust or displacement of adjusting screws for other reasons.

The following signs and malfunctions indicate the need to adjust the carburetor:

  • The engine starts with a strain and stalls almost instantly;
  • The consumption of gasoline is excessively large, the exhaust is too thick, the combustible mixture in the cylinder does not completely burn;
  • The factory settings of the carburetor of the chainsaw are shot down (due to vibrations or unsuccessful attempts to regulate);
  • malfunctions of the air cleaning system, which led to the fall of particles of garbage into the distribution of the fuel mixture of the mechanism;
  • Significant wear of the piston group. setting up the carburetor in this case acts as a temporary measure.

It is clear that when dirt gets into the fuel system with one setting, the problem cannot be solved. it is necessary to flush it. In the case of worn piston, major repairs are required. However, in all these cases, the carburetor is also adjusted.

The need for adjustment

Throughout the operation process, the need for additional adjustment and ensuring the proper supply of the fuel-air mixture periodically arises. How to determine when exactly and what setting must be performed for the normal functioning of the technique? There are characteristic features when the mechanism, according to the behavior of individual parts, himself suggests when adjustment is necessary.

First of all, every time before the next start of the engine, it is necessary to check the color of the spark plug electrodes.

By its change, you can make a decision on the need to adjust, commission work processes, improve the quality of the combustible mixture:

  • Black electrodes covered with soot or soil indicate a rewritten air-fuel mixture entering the engine.
  • Electrodes of brick gray color indicate that the mixture is ideal in composition and no additional adjustments are required to be carried out.
  • White plaque on the electrodes of the candle shows that the mixture is impleased.

The signs set forth in paragraphs 1 and 3 indicate that for the chainsaw STIHL 250, the carburetor adjustment is extremely necessary.

NOTE! DIY Carburetor adjustment of the STIHL 250 carburetor may be needed by the owner in case the fuel quality, height above sea level, or if the gas release arose at the place of operation of the chainsaw. Perhaps the humidity has changed, temperature, atmospheric pressure.

Accurate settings will achieve maximum performance of the unit when external necessary conditions for its operation are reduced. Successful debugging of operational regimes prevents oil fasting and failure of the engine due to insufficient lubrication. After all, the lubricant enters the saw cylinder along with the depleted fuel-air mixture.

Preparation for carburetor adjustment

The primary importance when setting all the characteristics of the dosage of the fuel of the STIHL 250 model is the highest adjustment screw located near the muffler. The factory setting, the parameters of which are shown on the upper plastic cover, provides that it should be twisted one revolution from a complete twist.

DIREHL 250 with your own hands is adjusted throughout the operation process. Writing the screw enriches the working mixture, since the air-fuel mixture receives a larger volume of gasoline, and tightening the screw impoverishes the working mixture, since the air fuel mixture receives less gasoline.

Adjusting the carburetor will not give positive results if there is an air leak on the engine side through:

Settling STIHL 250 carburetor is set up only after a careful inspection, identifying the existing air leaks. The next step in preparatory adjustment work is the full maintenance of all components and mechanisms.

  • cleaning from deposits, slag, resins;
  • engine washing using a solvent, acetone;
  • replacement of the spark plug;
  • cleaning, air filter washing;
  • Checking the tension of the cutting circuit;
  • idle setting;
  • warming up the engine to operating temperature.

Then you can proceed to complex settings manipulations.

Adjusting the gasopyle carburetor

Most chainsaws have three adjusting screws on the carburetor. In order about each:

  • T.Cooper screw. The idle screw is responsible for the position of the throttle, when the gas handle is completely released. If the throttle is not open enough, then the engine will stall with a released handle since the damper will block the supply of the fuel mixture. In the event that the throttle is open to a large value, then the chain will rotate, which is strictly prohibited by safety precautions when working with a chainsaw.
  • L-vint of low speed adjustment. This screw regulates the amount of fuel in the fuel mixture when the chainsaw is operating at idle. If the amount of fuel is large, then the engine will stall under load, if the fuel is not enough, then as a result. overheating of the engine, bullying, and so on.
  • H-vint of high speed adjustment. Is responsible for the amount of fuel in the mixture when the chainsaw. If this adjustment is configured for a larger amount of fuel, then the engine works “unacceptable” and smokes, and if less, we get too high speeds and overheating.

Carburetor adjustment step by step

  • Check the condition of the air filter. Remove it or or clean it or change it. If the air filter is clogged with mud and sawdust, the work of the chainsaw will not be normal.
  • Check the condition of the muffler. It should be clean and non.attached. about cleaning the muffler here.
  • Before starting to adjust the carburetor, it is worth filling the fuel tank by at least half.
  • If the chainsaw is able to start, then she should let it work for a few minutes to warm up. If the adjustment is carried out “for cold”, then the mixture will be re.enriched after warming up.
  • It is necessary to start adjustment by adjusting the idle speed of. It is extremely desirable to have a tachometer, then we focus on 2700 revolutions/minute. If not, then we need to find the highest speed at idle. In this case, the chain should not rotate. If it still spins (a chain of course, not the Earth), then we achieve its stop by rotation of the screw t. The sound of the chainsaw should be like when listening to the file below. https: // Benzopilatut.ru/WP-Content/Uploads/2016/01/chainsaw-on-cold.WAV
  • We adjust high turnover- screw h. If we rotate it for a clock, then the turns will increase, and if you fall against the sentry. Twist it until the failures appear in the ignition. After that, turn it into about one fifth turnover. The sound of a chainsaw when working at maximum speeds should be the same as when listening to the file below. https: // Benzopilatut.ru/WP-Content/Uploads/2016/01/chainsaw-maximum turnover.WAV
  • We check how the chainsaw is gaining momentum. She should type them evenly and quickly. If the revolutions grow slowly, then we turn the screw L slightly.

Device and principle of operation

Before starting adjustment, it is recommended to study the device of the chainsaw carburetor in advance in advance. Most often it does not depend on the model, only Chinese.made chainsaws may be exceptions. But you can always spy in the instructions.

The carburetor is part of the chainsaw engine, which is responsible for mixing oxygen and fuel in the correct proportions and supplying the mixture directly to the engine.

It is important that the proportions are observed at the same time, otherwise there is a risk of failure of the engine, which can be manifested by an overexposure of fuel or a complete stop of the device.

The main parts of the carburetor of the gasoline saw are:

  • tube. performs the function of air transmission, the portioned supply is possible due to the presence of the damper;
  • Diffusor. this part is located directly at the input opening, through which the fuel is supplied, can accelerate the flow of air;
  • The sprayer is able to inject gasoline into the created air flow;
  • The float chamber is a cavity, serves to maintain fuel at the same level, from it, gasoline through a nozzle is supplied to the spray.

The principle of operation of the carburetor of the chainsaw is simple. Its structure allows air to pass through the tube, while the speed can be adjusted by the damper. After the tube is open, the float is activated. This leads to the fact that the air passes through the diffuser and mixes with the combustible. Further, this mixture moves into the cylinder. Due to the difference in pressure (in the chamber with the float it is almost equal to the atmospheric, and in the tube-rarefied) fuel is absorbed into the tube, while the larger, the more revolutions of the motor motorcycle engine.

For an independent option of the carburetor, it is necessary to familiarize yourself with its device and understand the work order that is carried out to adjust the parts responsible for the correct functioning of the components of the device and the parts close to it.

It is necessary to carefully handle objects for the option, also determine the compliance of the displayed characteristics of very acceptable values.

About the device of the carburetor

The carburetor serves to mix the combustible consistency with the air, subject to in advance of the established proportions in advance. If clear doses are not respected, the serviceability of the motor is under danger. When a huge amount of air acts during mixing, and fuel is not enough, such a mixture is considered the “poor”.

Drinking must not be allowed, because with a large amount of fuel for comparing air, malfunctions in operation or wear of the motor are also likely to. The carburetor adjustment is needed not only before the initial implementation, and when any differences in its work are detected. Before working with a chainsaw, do not forget to carry out its run.in.

The design of the carburetor contains a standard set of parts, but may slightly change depending on the manufacturer. Components:

  • The foundation. This is a special tube that is visually similar to an aerodynamic structure. Air passes through it. In the transverse direction in the middle of the pipe there is a damper. Its position can be changed. The more it is extended to the passage, the less air enters the engine.
  • Diffuser. This is a lean part of the tube. With its help, the speed of air supply increases in the segment from where the fuel comes out.
  • Fuel supply channels. The fuel mixture is contained in a float chamber, then passes into a jick, from which it flows into a spray.
  • Float chamber. What is the distance at the starter from the poles to the module?, What is the proper adjustment of the carburetor of the chainsaw?, STIHL 250 ms. Is a separate structural element, resembles the shape of the tank. Designed to constantly maintain the optimal level of fuel fluid in front of the entrance to the channel, from where the air comes.

What to have for configuration

Each owner of the carburetor must have the necessary tools to adjust this system. There are three adjusting screws that are located on the device case. They have their own markings:

  • L. screw for correction of low speeds.
  • H. screw for adjusting high speeds.
  • T. regulates the idle speed, in most cases it is used for experiments.

Before adjusting the carburetor, you need to prepare the device:

  • The engine warms up, that is, it starts about 10 minutes before the repair, and turns off at the beginning of work (see. how to get a chainsaw).
  • Air filter is checked and washed.
  • The circuit stops by turning the screw t to the stop (see. Oil for the chain).

To carry out safe repair, you need to prepare an even surface, where you can carefully place the device, and turn the circuit in the opposite direction. Need a tachometer. It determines the presence of a violation in the carburetor. The price of a remote assembly for a carburetor StiHL adjustment of the carburetor video. Chainsaw. When revolutions, the sound should be perfect and absolutely even. If screaming notes are noticed, then the mixture is oversaturated.

Setting instructions

Carburetor adjustment is divided into two main stages. The first is called basic. It is produced when the engine is turned on. The second is performed when the engine warms up.

To carry out the carburetor setup procedure successfully, you need to familiarize yourself with the instructions for the operation of a particular model in advance to identify additional features of configuring the device.

First stage

The adjusting screws of the highest and low revolutions should be closed clockwise until the moment of the highest resistance. When the screws reach the stop, you need to translate them in the opposite direction and leave them with 1.5 turnover.

The engine turns on for average speeds and warms up for about 10 minutes. The screw responsible for adjusting the idle stroke should move clockwise. It is released only when the engine arrives in the stable functioning mode. Need to be controlled so that the chain does not move during this process.

In idle mode, the engine may stall (reason. here). In this case, you need to immediately bring the adjusting screw clockwise to the stop. Sometimes the chain begins to move. In this case, the adjusting screw should be twisted in the opposite direction.

Checking the acceleration work

You need to perform a small study. The acceleration of the operation of the device is initiated. The serviceability of the engine should be evaluated during maximum revolutions. When the engine functions correctly, then when you press the accelerator, the speed increases rapidly to 15,000 rpm.

If this does not happen or an increase in speed is too slow, it is necessary to apply the screw marked with the letter L. He turns counterclockwise. Moderate movements must be observed, since the turn cannot be more than 1/8 from the full circle.

Dismantling the carburetor Stihl 180

In order to blow, change the gaskets or needle valve, the carburetor must be disassembled. To do this, you need to promote 4 screws on the lid of the compensator and one on the fuel pump.

Having opened the case, you should be extremely careful, t. to. If garbage enters into the inside of the carburetor will make his work impossible. The thickness of the channels in it is comparable to the thickness of the thread or even the human hair.

I would like to once again note that the STIHL carburetors, which are produced by its subsidiary Zama, are very reliable. With proper operation and storage, they are able to serve the allotted chainsaw without repair.
