Chinese chainsaw does not start a spark eat. Malfunctions leading to the wrong…

Why the chainsaws not start the causes and methods of elimination. How does the mechanism work

Almost all tools, and foreign ones (Husqvarna, Makita, Stihl, Partner 350), and Chinese chainsaws, and domestic (friendship, Urals) are arranged the same way. Therefore, to find the reason why the device does not start and stalls is not difficult.

There are four elements in which problems may arise:

  • Fuel for which the carburetor is responsible;
  • Lubrication;
  • The air that enters the air filter;
  • Spark, the quality of which depends on the ignition unit.

All of them depend on each other and interact with each other. If any element works incorrectly, then the saw stops working.

To begin with, all the tools start in different ways-on hot and cold. Two frequently used mechanisms are responsible for this process.

Be sure to see what is written in the user’s instructions. It indicates that when turned on, it is necessary to make sure that the emergency stop brake is recorded. But it is much more difficult to start a saw with a brake, so sometimes it is better not to turn on the brake.

As you can find out from the instructions, there are a fuel tank and engine inside the case, and the saw part (tire with a chain), handle and starter are outside.

First you need to figure out how exactly the tool does not start. For example, the saw starts up, but immediately stalls, or loses the power of work, the quality of the saw.

Perhaps interruptions in the work occur due to problems in the engine. But I would not recommend it immediately to disassemble it. It is better to look for a problem from the simplest option.

It is very important to take into account the quality of fuel. If the mixture is prepared incorrectly or has deteriorated over time, then even such reliable tools as the Urals or Husqvarna 145 will not work. The instructions must indicate proportions and special oil for your chainsaw.

Another common problem. during the start, the user floods the candle. It needs to be examined if it is completely dry, then the fuel does not go to the cylinder.

If you see a black fuel or a lot of fuel, then perhaps the carburetor incorrectly regulates fuel supply.

If your saw.tool starts up, but immediately stalls, then the problem needs to be sought by a jacket of a carburetor or a fuel filter. Perhaps they clogged.

In order to check if the saapun is damaged, it is necessary to disconnect the fuel hose from the carburetor and see if the fuel mixture flows from it.

If the saw does not start hot, then the problem can be in the muffler. Sometimes it clogs from the exhaust itself.

Often often a saw breakdown occurs due to a small amount of lubrication for the circuit. This happens with clogged channels or leaking oil pipeline.

Also inspect the connections of the tubes with oil pumping fittings, do they leak.

Very bad when the breakdown arose in the cylinder. When examining it, you can detect irregularities or chips, this may be the cause of the problem.

STIHL 180 chainsaw is not started? Prerequisites and decision!

Today, the manufacturer of STIHL occupies a leading place in the middle of other companies that create the production of equipment created for agricultural and the construction of work. The products of this manufacturer are famous not only for its highest level of properties, but also, also a good pricing policy and the power of its models. This is one of the most recognizable global companies.

Surely it is quite difficult to meet a person who would not have a chainsaw of this brand. But the fact that out of 10 probable 6 people definitely have them. Why the chainsaw is not started if it does not start. The reasons for what questions are you not. And this is not breathtaking, because the stihl chainsaws are flush with elegance of design. But to regret, and such giants of technology from time to time fail and require a certain kind of repair. Now we will pay attention to one of the moles of this manufacturer, and specifically the chainsaw of STIHL 180. The chainsaw is poorly started to a cold violation of the sequence of actions when starting to cold. About the chainsaw of Stihl MS 660 Read here. So, let’s get down.

Replacing the crankshafts of the Chinese chainsaw. Replacing the oil seals with a chainsaw: Stihl, Ural and others

Today, many users do not do without high.quality chainsaw, because in household tasks it helps to cope with various wood, branches and harvesting of firewood. Thus, the tool should always be in good condition, for which make diagnostics and repair of the desired element in a timely manner.

Depending on the model used, details and small oil seals can be of different quality. Replacing the oil seals on the crankshaft and other elements is responsible, although it takes a minimum of time. ELks are created from rubber of increased strength, but over time they flow, and timely replacement is required. When the oil seal cracks or receives a defect, oil begins to leak, which entails a breakdown of the entire engine. Therefore, when determining the problem, carry out a quick replacement with a similar part.

Each chainsaw, regardless of the brand and the price has the same design, so more often the oil seal proceeds in the crankshaft area. Also, seals are located in all rotating mechanisms of the saw, if possible, check them. If you are minimally versed in the design of the chainsaw, then getting to the omentum will not be difficult. Just remove all the elements that interfere with the access to the crankshaft.

Please note: there are 2 oil seals on the crankshaft, one at the beginning of the crankshaft, the other at the end. The part reliably compacts the inner part of the engine, closing the bearing. Without this oil seal, the oil will whip in all directions, so you can determine the breakdown by butter of the oil from the crankshaft.

How to remove the stihl chain of the chain of chainships?

Regardless of the brand of the chainsaw or its design, the removal of the oil seals is performed using a similar technology. When you got to the broken part, carefully remove the oil seal. This is done in several ways:

  • Using a special puller, but monitor the oil does not come out of the crankcase;
  • A cheaper and simple way is to pick out the oil seal from the groove with a sharp object;
  • If the part sits tightly and its size is sufficient, you can go in an old proven way. screw it into the oil seal and pull it with pliers.

The old oil seal is not necessary to protect when dismantling, but the main thing is not to damage other details of the chainsaw. If we are talking about branded, then it is better to do work in specialized services. It is also better to buy an original oil seal, practice shows that cheap analogues start to leak quickly.

chinese, chainsaw, does, start, spark, malfunctions

A new oil seal is put on is quite simple, it must be pressed in the landing hole with a puller or another item. The main thing is that he enters evenly and does not stick out. You also need to do everything carefully, since the rubber part is easily damaged. The dimensions of the chainsaw oil seals can be indicated in the old sample, or they are easy to choose according to the model of your chainsaw. As you can see, the replacement does not cause any complexity, similarly to be carried out with other oil seals.

Repair of a gas handle of a chainsaw. DIY DISCOUNSION AND ACHIEND

The low level of technical equipment of many service services and the high cost of their services forces many owners of faulty chainsaw equipment to repair their gadgets on their own. How to disassemble a chainsaw, replace faulty parts, and also correctly collect a chainsaw with minimal time and means?

Independent disassembly of a chainsaw suggests the presence of spare parts, the corresponding tool and locksmith skills. It is possible that for the dismantling of individual parts you will need special pullers, the manufacture of which will take more time than the repair itself.

In a number of modern models of domestic and semi.professional chainsaws, for the dismantling of the drive sprocket of the saw chain, special keys that are not included in the attached kit are used.

Problems of independent repair

The problem in many cases is complicated by the lack of full.fledged information on repair technology. According to foreign manufacturers, after the development of the saw, the saw should be written off in the scrap, so the maintainability of many budget level models causes reasonable doubts.

They are more difficult to restore a professional class chainsaw.

  • The problem is complicated by the high cost of spare parts.
  • It is possible that to restore the performance of individual nodes and mechanisms, in particular, special equipment will be required to set up fuel equipment.

Replacing expensive branded parts affordable in cost, but in short.lived Chinese analogues in economically does not justify itself. Practice shows that these components produce a resource at best by 50-60%.

The algorithm for determining the malfunction

The reason for the refusal of the saw or the deterioration of its performance may be:

  • a clogged battleship cover;
  • Air sucker with a carburetor due to the destruction of the gasket or weakening of threaded fasteners;
  • Mechanical sequel of removable saw equipment and other minor defects.

HOW-TO Fix A Chainsaw With No Spark. Ignition Module Replacement

Before starting disassembly, you should verify the need for a more volumetric repair.

Independently assemble a new chainsaw after repair with initial quality, most likely it will not be possible. In the design of modern chainsaws, press plantings of conjugated parts are often used, which have minimal maintainability.

Even a partial analysis of a chainsaw with an improvised tool can lead to undesirable consequences. In most cases, to eliminate a malfunction, you can limit yourself to the dismantling of a separate node or system.

Tips for the dismantling of different nodes and systems

Only general recommendations can be given in the volume of this article, since chainsaws from different manufacturers may have significant technical differences.

Before disassembling a faulty tool, it is necessary to dismantle the saw headset, drain fuel and oil from gas tanks, clean the inaccessible places of the chainsaws from surface pollution.

Fueling system

Disassembling the carburetor requires special attention. This node consists of many small parts, so the removed parts in a given sequence are laid on a clean sheet of paper. After washing all components, the carburetor is collected in the reverse order.

Compression restoration

Less complex repair of the piston group. To dismantle the cylinder, it is enough to remove the threaded fasteners, lay the saw to the side to eliminate the slices of the destroyed compression ring, the piston skirt or other extraneous objects to get into the crankcase of the engine.

The cylinder mirror wears out unevenly, so the installation of a new piston does not give a significant effect. As a rule, during major repairs, after checking the suitability of the crankshaft, a full set consisting of a cylinder, a piston of a compression ring and a piston finger is installed.

Repair of the starting device

Dismantions of the starter for replacing the cord for an experienced user do not create problems, but the plastic case in most cases is not subject to repair.For the most part, are copies of the most popular European models, so we analyze the Chinese chainsaw according to the standard scheme.

Worn details of the saw headset are not restored.

  • At home, you can shorten a new chain for installation on a shorter tire.
  • The resource of branded components of tires is equal to the resources of three saw chains.
  • This indicator can be significantly reduced by the wrong choice of chain step or a large wear of the crown of the drive star.

Finish work

In a number of models, the engine control elements, launch blocking and emergency stop systems are displayed on the handles, to the operator’s hand seizure place. It is recommended to assemble the chainsaw handle after preliminary cleaning of the contacts of all electrical and mechanical communications.

Self.assembly of a chainsaw is part of the repair work that requires special attention. The success of the final result is facilitated by the correct sequence of operations, a fairly high quality of parts, gaskets and other consumables.

How to remove and replace the leading star

Moving the chain along the tire is carried out by the leading star, which is connected to the gearbox. It is a assembly unit rotating due to the bearing. At the end of the tire there is a driven star with the same step in relation to the leading. Therefore, during the repair work, all factors are taken into account: the coincidence of the slots, the presence of bearings, the cinematic of the tool.

chinese, chainsaw, does, start, spark, malfunctions

When we wear the slot, the leading star is replaced, otherwise there will be no adhesion to the chain.

In order to change the detail, you must perform the following actions:

  • unscrew the nuts of the tire cover and remove the headset using working tools;
  • remove the air filter;
  • unscrew the candle of saws;
  • ;
  • inspect the drum and check the crown;
  • ;
  • if necessary, replace the broken part with a new one;
  • collect all the details in the reverse order.

If the process of replacing the sprocket on the Husqvarna chainsaw is difficult, use the services of a specialist.

The chainsaw started up and will not start anymore

The prerequisites why the chainsaw is starting and stalling

Basil has long been not a luxury, but the right equipment for those who have a country site or household. But, just like no matter what other technique, such a tool has the ability to fail, regardless of a simple device.

The systematization of the main defects contains:

  • complete absence of a motor factory
  • The engine starts and stalls
  • The unbalanced work of the tool
  • Stop work at load
  • Loss of power.

If the chainsaw does not start at all, the reason and perhaps subsequently:

  • Manufacturing defect
  • Lack of fuel
  • Difficulties with starting a complex of accounting ignition programs
  • Lack of spark from the spark plugs
  • Poor fuel mixture
  • Clothing carburetor
  • Obstacles with a high.voltage wire
  • Lack of compression.

Why is the chainsaw starts and stalls, what to do here? You need to carefully discern the prerequisites for this purpose.

The chainsaw starts and stalls: reason, video

The reason that the chainsaws may stall immediately after the plant lies in the problems of a certain part of the equipment.

  • The most obvious prerequisite for why the chainsaws started and stalled, may be a small level of fuel in the tank. The evidence of this is the stop of the tool when tilted, when the remnants of fuel accumulate in a certain place of the fuel tank. With poor fuel, a non.bustle with the service of the chainsaw may also appear, then it is necessary to change it absolutely.
  • Blockage of the sapuna, which significantly reduces the fuel consumption to the engine.
  • The missing contact of the cap with a candle, which leads to a strong heating of the candle insulator. Contact deterioration may appear due to mechanical shift in another case.
  • Damage to the spark plugs.
  • The muffler blockage, due to which the output of the exhaust gases is aggravated, leading to the stop of the motor. Therefore, the chainsaws can start and stall at idle. The sediment in the muffler can also appear due to poor fuel or incorrect operation of the tool.
  • The bad adjustment of the carburetor.
  • Damage to the piston group
  • Difficulties with a fuel filter on a different pump. With all this, gasoline can flow through the pump or poorly flow through the fuel filter to the carburetor. Ultimately, the chainsaw starts stalling with increasing speed.
  • Air filter pollution. Difficulties with this element of equipment are given for the fact that, with high loads on the engine, he simply does not cooperate with it because of the blockage and stops. A similar result also comes out with an increase in speed.
  • Closing the chain due to the absence of it, as it is also called the missing amount of lubrication, additionally problems with the brake of the chain.

Often they are brought to the repair of the Basil. Alas, it happens. This time brought with obvious.

Why the chainsaws are poorly starting and stalling

With a bad launch of equipment “on a cold” inconsistency, you will like more without compression, t.e. the rings are worn out due to a long service life, their substitution is required. With the prerequisite that the engine is poorly started in a non.heated state, there is an inconsistent with a silencer, and in addition, the bad contact between the candle and the wire.

Also, the reasons for disgusting starting will be wear or damage to the gasket, a rubber cuff in the accelerating pump of the carburetor, due to which an additional air flow appears, leading to an increase in the speed of the saw.

Elimination of problems

The operation of the equipment is suitable for the correct, with a repeating inspection of the components of parts to prevent breakage. To remove problems, you need to check what remains to our client components of the equipment for their functioning.

If the chainsaw is started and stalls, the reason will be possible to be eliminated at home. If it consists in a lack of incorrectly prepared fuel consistency in other words, you need to correct it. For the prevention at one time, the downtime of the chainsaw should always be drained the remnants of fuel.

Read chainsaw STIHL 250 does not start the reasons

It is necessary to conduct a repeated check of the spark plugs. At the same time, the soot that scores the clearance of the connection should be removed, and additionally inspect the tips for the presence of fuel. An additional prerequisite for problems with spark plugs and possibly wet them with gasoline. For this purpose, they must be removed, wiped with a rag and quit drying. Faulty candles are replaced.

In the absence of a spark between the light of the ignition and a high.voltage wire, however, if there is a good connection, it is necessary to replace the ignition unit.

The muffler blockage is a frequent prerequisite for the breakdown, with which the chainsaws are engaged and stalls right away. To eliminate the malfunction, it is necessary to dismantle the silencer, clean it from the soil using sandpaper or a special chemical solution. If the model of the chainsaws is indispensable, chemical substances are poured into the system and there is a clock there, then it is blown.

The carburetor must be adjusted if the chainsaw

stalls at idle. A clear setting is a fairly laborious process, therefore it is usually done in service centers. However, on certain models there are elements for its option, just turn the bolt by half a turn to increase the rupture of the chainsaw, the problems will be eliminated. In case of sucker, nozzles, channels and filters, you need to disassemble and clean the entire carburetor. With the wear of the seals, gaskets, cuffs, you need to change them by preventing the “sucker” of air.

The chainsaw is not started? Reasons and solutions

Basils have long been a kind of innovation and even more so are not considered exclusively a professional tool, because today literally every owner has such a universal device in his tools. And although there is a huge variety of types and models of chainsaws, in general, their designs do not represent something particularly complicated. With proper use and maintenance of this tool, any problems with its work arise quite rarely. But what to do if a chainsaw does not suddenly start? The main thing is not to panic and in order to figure out what is the reason for the problem.

First you need to check the fuel level. If it is not enough, it is necessary to correctly prepare the fuel mixture, which should include the proportion of gasoline/oil indicated in the operation instructions (the oil brand is also indicated in the instructions). To prepare the mixture, use AI-92 gasoline correctly-this will get rid of many unnecessary problems. The amount of the mixture should be designed for 1-2 weeks of the chainsaw, gasoline has a feature of losing its octane properties.

The tool may not start because during its launch flows a candle of ignition. If this is true, then to solve this problem, it is necessary to turn the flooded candle and be sure to dry it (without pumping), drain the fuel from the candle hole and make a half.hour break. Then install either dried or spare candle in place. It is also important to pay attention to the contact between the tip of the candle and the high.voltage wire.

The completely dry light of the ignition suggests that the fuel mixture does not occur, which means that there is a certain problem with the carburetor. First you should clean the fuel filter. If after eliminating all available pollution, nothing has changed, it is necessary to do a carburetor. However, it is better to entrust its disassembly and cleaning to specialists in this matter.

If there is a spark, but the chainsaws still do not start, you will need to additionally check the air filter and the saeph. Air filter is easily cleaned of dust. In order to check whether the sapphone has clogged for leveling the pressure in the gas tank, it is necessary to disconnect the fuel hose and see how the fuel flows from it. If the stream is normal. the saopant is in order if there is no fuel or it flows very slowly. you need to clean it.

New chainsaw will not start

Often a completely new chainsaw cannot be launched the first time. With a cold launch of its engine, the switch is installed so that the damper is closed. Now you need to pump up the fuel into the carburetor, and then twist the launch hand well. It is considered normal, even if after 2-5 launches the tool starts up, but stalls. After that, you can transfer the switch to the position of half.gas, and then to the working position, and continue to start a chainsaw.

The reason that after the winter period the chainsaw refuses to work, it may be elementary. the fuel mixture has decomposed and lost its properties. To eliminate this problem, it is necessary to pour the old fuel, unscrew and dry the spark plug, season the chainsaw with a new fuel mixture and abundant the engine several times. After installing the candle in place and in the absence of other problems, the chainsaw will necessarily start.

Malfunctions of the chainsaw

Chainsaws are simple in design and work units. With proper treatment of it, malfunctions rarely occur and, often, they are quickly eliminated by the owner himself.

Our review is designed to help in extreme situations when it is necessary to understand and eliminate the basic causes of the instrument malfunction.

The chainsaw is started normally, but when adding gas stalls

One of the common breakdowns of household chainsaws is only at idle, and an instant refusal when pressing a standard gas trigger.

There can always be several reasons for this malfunction:

  • clogging or initially incorrect setting up a standard carburetor. in this case, you will need to clean the knot and configure it according to the instructions in the instructions for operation;
  • The clogging of the basic air filter of the tool used-because of this, the air does not enter the saw carburetor, which leads to a gradual loss of power;
  • The clogging or wear of the fuel filter. as a result, the part is not capable of missing the amount of fuel that is necessary for the ability to set the revolutions of the motor.

If the chainsaw works normally at idle, but stalls under load, then the first thing its owner should do is check the condition of the filters. Only after that can you start setting up the carburetor.

Checking the filing of the combustible mixture and ignition system

First of all, you should make sure that there is a fuel in the float chamber of the carburetor. After several attempts to launch the engine, the twisted candle dry will tell you that the reason for the poor launch in the absence of supply of the combustible mixture.

Recommended sequence of actions:

  • Fuel filter check;
  • pattern;
  • the purity of the drainage hole of the fuel tank cover;
  • freezing of the float valve of the carburetor in a closed position is not excluded.

To clean the volume of the cylinder, it is necessary to make several energetic jerks with a starter when the candle is removed and the ignition is turned off. In the absence of a new, obviously serviceable candle, it is necessary to carefully dry and check the old one on the spark. It is not desirable to warm it over open fire, since the probability of the formation of the insulator cracks and its full failure is great.

chinese, chainsaw, does, start, spark, malfunctions

To check sparking, a candle with a dressed cap must be applied to the saw housing and crankshaft crankshaft with a starter. The working candle gives out a strong discharge, accompanied by a characteristic crack.

Small, with a red shade, the spark indicates a malfunction of the ignition unit, high.voltage current.lamp or internal resistor of the standard nursing.

There is no spark on the chainsaw of Stihl 180

The main malfunction, due to which the chainsaw of the Stihl MS 180 is not started, may be the absence of a spark between the electrodes on the spark plug. Signs of this malfunction can be detected if you unscrew the candle and inspect. Having discovered when examining that the candle is wet, it is necessary to proceed with the search for the reason for the absence of a spark on the spark plug.

The spark plug is faulty

The first thing to do is to check the performance of the candle.

It is quite easy to do it. The candle is inserted into the cap of the high.voltage wire and pressed to the engine cylinder, after which the starter moves several times if the spark is not observed between the electrodes, then it is faulty or faulty of the ignition module.

Checking the sparking candle is carried out with the ignition on.

In order to find out for sure that the problem is in the light of the ignition, it is necessary to check the obviously serviceable similarly. If the spark appeared as a result of checking, then the problem was found and replace the candle with a new one to eliminate the malfunction.

Problems with ignition coil

The ignition coil, it is also called the module has a non.graceful design, therefore it is very difficult to determine its performance without a special tool. If the spark on the working candle has never appeared, there is a suspicion that the reel is to blame. But do not immediately take off the old coil and run to the store, problems can have a slightly different character.

There is no gap between the flywheel and the ignition module

In some cases, the absence of a spark on the spark plug is explained by the wrong clearance between the contacts of the ignition module or flywheel. It may be larger, and it may also not be at all, and then scratches that were formed as a result of contact with the contacts of the coil will be observed on the surface of the flywheel.

Check and set a gap without a special tool. you can. To do this, you need to remove the starter, weaken the two screws of fastening the coil and laying the plate cut out of the plastic bottle between the contacts of the flywheel and the ignition module, tighten the screws of the module mounting.

If, after such adjustment of the gaps, the spark appeared, everything is in order, you can continue to work with the chainsaw of the Stihl 180, if not, you need to re.examine and check if the flywheel will touch the coil contacts again. Suppose as a result of the audit found that after adjusting the clearance, it was gone again. So the reason is most likely in the crankshaft bearings.

Defective crankshaft bearings

With a defect in the crankshaft bearings, a small backlash is observed on it. Check the presence of a backlash you can with a stroke of the flywheel of the chainsaw of Stihl 180 from side to side. If there is a backlash, then under the influence of its magnets, the flywheel is attracted to the contacts of the ignition coil, t. to. The backlash on the bearings allows him to do this and as a result the spark disappears.

Replacing crankshaft bearings

Replacing crankshaft bearings is better in a specialized service, t. to. When replacing, you need to completely disassemble the Stihl 180 chainsaw and remove all its main nodes.

Without certain experience or at least repair skills of similar chainsaws, to replace the crankshaft bearings qualitatively, it will not work.

So, we figured out the lack of a spark, but what to do if there is a spark, and there is no answer to the question why the chainsaw of the Stihl 180 is not started. The reason can be hidden in the fuel system.

Pollution of the main filter elements of the chainsaw, adversely affect its work.

For example, a dirty air filter will provide air supply to the carburetor in full, which will affect the quality of the fuel mixture and normal engine start. Fuel filter pollution will make it difficult, or even reduce the supply of gasoline to the carburetor and make the engine to work impossible.

Reduced compression

As you know, for the normal launch of the chainsaw in its engine, compression should be present. It is necessary for the normal compression of the fuel mixture in the engine cylinder, it also affects the operation of the gasoline pump.

During the operation of the tool, the value of the compression indicator falls, and the chainsaw begins to start poorly.

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

A sign of reduced compression is the weak resistance of the starter during the start. With reduced compression, a decrease in the power of the chainsaw is observed, which negatively affects its performance. The problem of replacing piston rings, or completely CPH, is eliminated.

Carburetor adjustment

Not correct adjustment of the carburetor will cause the chainsaw will not develop full power. It will be bad to start, or not start at all. The setting of the carburetor directly affects the quality of the fuel.air mixture, which is necessary for normal starting and further engine operation.

If the carburetor is improperly adjusted, the fuel with the air will be present more, or less gasoline than required, and the mixture will not be ignited even with normal sparking.

Excess gasoline in the mixture, it is customary to call overflow. Characteristic signs of overflow, it is a wet spark plug, after several unsuccessful attempts to start a chainsaw.

Spark plug

Spark plug is one of the main elements of the ignition system. On its electrodes, a spark is formed, and when this element fails, it will be difficult to start, or it is not at all possible.

The candle can completely refuse, or work with interruptions or give out a weak spark. Checking the candle is quite simple, for this you will need to unscrew it from the engine, attach to the cap of the high.voltage wire and, putting it on the cylinder, pull the starter. If the candle is in order, the spark will be powerful with a bluish tint. Weak spark with a reddish tint, a sign of a problem. A defective candle needs to be replaced.

Ignition coil

The reason that a new chainsaw is not started, or it starts poorly, may be a ignition coil. Modern chainsaws are equipped with electronic ignition coils. This part is not subject to repair, and, as a rule, in the presence of a defect, it completely changes.

Gap between the ignition coil and flywheel

An unbelievable gap between the flywheel and the contacts of the ignition coil affects the quality of sparking, which in turn is responsible for the normal start and stable engine operation.

The chainsaw is not started on hot

In cases where the chainsaws do not start hot, you need to conduct a visual inspection of all the main nodes of the chainsaw. Inspection should start with the spark plug. Check the spark, inspect the surface of the candle electrode, these actions will help establish the direction in which you should look for the problem.

Malfunctions in the ignition system

If, when examining a candle, it is found that it is wet and sparking on the contacts does not occur, this means that the problem should be sought in the ignition system, inspect the coil, check the gap between the flywheel and contacts of the coil. You can also check how tightly the cap of the high.voltage wire sits on the candle, and the candle itself. Try to replace it with a new.

Problems in the fuel system

If during the examination it was found that there is a spark, and the candle is dry, it means that the problems are in the fuel system. Its check should start with the fuel filter. Next, you need to inspect the fuel hose and its fastening to the carburetor, pay attention to, on the fuel leaks from the carburetor and the presence of gasoline in the air filter housing. It is advisable to start removing the carburetor only if the visual inspection did not allow determining the cause of the breakdown.

A characteristic feature of the problem in the fuel system is an excessive amount of fuel in the engine cylinder. As a rule, the signs of this are an overly wet spark plug and the presence of a spark on the contacts of the candle. In this situation, it is necessary to turn the chainsaw so that the candle hole is directed to the bottom. If gasoline will flow from the cylinder, then the reason that the chainsaw does not start, it is transferring fuel to the engine.

“Floods” with fuel, sometimes due to improper adjustment of the carburetor, or its malfunction.

The process of adjusting the carburetor can be found on the example of the Champion 254 saw, watching the video instructions.

The consequences of operation on a rich and poor mixture

Confirmation of normal, in a proportion of 16: 1, the quality of the air fuel mixture is the brown color of the insulator and the absence of traces of soot.

Condition of the air intake and muffler

The cause of the problem launch may be the filter of the air cleaner clogged with sawdust. If the engine starts with the air intake removed, special attention should be paid to cleaning the filter. A large amount of soil in the muffler is reflected in the power and thrust of the power unit, but the engine should be launched without much effort.

When the threaded fasteners are weakened, an air leak is formed, which leads to the depletion of the gas-air mixture and, accordingly, the deterioration of its working characteristics.

To replace the damaged gasket, it is recommended to use the repair kit, in its absence, the gasket can be made from the elegant benzo-grease material in the thickness of the thickness.

Adjustment of the Partner 350 chainsaw carburetor with your own hands

Before you start setting up the standard carburetor of the Partner model, you need to carefully clean it of dust, dirt and soot accumulated on the walls. In addition to the carburetor, you need to rinse and dry the fuel and air filter. Otherwise, the operator will not be able to accurately set the required engine speed.

In the left of the upper part of the protective plastic case of the Partner saw, holes are located, inside which the manufacturer provides bolts for adjusting the carburetor. Having found them, you can proceed to the base setting of the node. For this, the left and right screws responsible for the number and quality of revolutions, respectively, must be installed in a fully twisted position. Immediately after that they must be loosened for 1/5 turnover. The third adjusting bolt indicated by bean ts must be left in the position in which it is established.

The final configuration of the Partner 350 chainsaw carburetor is performed in the following order:

  • First, the saw needs to be started and allowed to work it for full heating;
  • After 5 minutes, you can start adjustment. At first, the left bolt must start turning along the hours of the clock until the time the engine does not gain maximum speed.
