The New Stihl Chainsaw Will Not Start
Stihl 180 chainsaw does not start: main reasons
The Stihl 180 chainsaw does not start: what can cause problems in the operation of the Stihl 180 chainsaw, how to fix them.
The saw in question can be considered a compact option, because its weight is only 3.9 kg. At the same time, it has a large oil and fuel tank. The device helps to perform its working functions by a two-stroke engine, the power of which is sufficient for solving simple tasks. In addition to this, during operation, this instrument does not generate strong noise, the level of which does not exceed 98 dB. For ease of understanding, it suffices to say that human speech creates noise at the level of 76 dB.
- The Stihl 180 chainsaw has a power of 2.6 watts. In principle, this is sufficient, bearing in mind that we are talking about a tool for household use.
- The capacity of the oil tank is 0.145 liters, the fuel tank is 0.25 liters.
- The tire is designed to measure 350 mm with a pitch of 0.325 inches.
As with other saws, the carburetor acts as the main starting device. Considering in more detail the carburetor with which the Stihl 180 chainsaw is equipped, it should be noted that it has a single tuning screw. In other words, it is a kind of idle speed adjustment screw. In this case, the jet, which has a full load, is stationary all the time.
In other words, the regulation is not applicable to it. In turn, there is no way to influence the full load in any way. You also need to pay attention to the factory settings, due to which the supply of the air-fuel mixture is carried out directly to the engine. Over, this principle is maintained regardless of the operating conditions of the tool.
Defective spark plug: troubleshooting methods
- Sometimes during the check it is possible to find out that the problem lies in a faulty spark plug. In this case it is removed, then allowed to dry. Some owners may try to ignite it, but this should not be done, because otherwise this element will be damaged and after that it will only be necessary to throw it out. During troubleshooting, you will have to remove excess fuel by draining it through a special hole.
- You also need to keep in mind that the drying time should be at least half an hour. After completing such an operation, you can return it to its place, and then test it in action.
- In some cases, the candle may fail due to develop your resource. Usually, when this is confirmed, the only option is to find a replacement for it. In this case, it does not hurt to have a spare candle, or even better, when you have a whole set of such elements at hand. In this case, you can always put a new plug instead of the existing one and make sure whether the broken plug is the cause of the breakdown.
- At the same time, the inability to start the chainsaw can be caused by poor contact, provided by the high voltage wire and the end of the candle. The problem with starting the chainsaw may be due to the failure of the ignition unit. In such situations, the only solution to the problem is to replace the faulty unit, since it is not repairable.
Stihl 180 chainsaw does not start: main reasons
Today, many manufacturers are engaged in the production of units for agricultural and construction work, among which the most demanded is the equipment manufactured by Stihl. The high level of quality is not the only reason why the products of this manufacturer are popular in the market. This was also facilitated by the democratic price and optimal power that the models of this brand have.
It seems that many had to use a chainsaw of a similar brand. And not just use it, but regularly perform a wide variety of work and make sure of the high performance characteristics of this tool. Such a proliferation of these products is no coincidence, given that, in addition to power, this instrument stands out for its graceful design. However, one must remember that this is still a technique for which the resource of work is limited. Therefore, each owner of such a unit at some point is faced with the need for repair. Next, we will talk about the features of repairing the Stihl 180 chainsaw.
Saw won’t start: reasons and solutions
- Speaking of the saw 180, it must be said that this tool has many advantages. At the same time, this unit is not without its drawbacks. Attention will be paid to them.
- It is a common situation that many owners find themselves in when the Stihl chainsaw does not start and floods a candle. This is usually attributed to the formation of a leak in the oil used to lubricate the chain. The same happens for the reason that over time, the area where the hose of the oil pump and the oil tank is joined loses its former tightness.
- In principle, this problem is solvable, however, in order to do everything correctly, you need to take into account the design of the chainsaw in question. By itself, this process provides for certain nuances, first of all, it is necessary to disassemble the unit, and without this it will be impossible to get to the required place.
- For many owners of this saw, the question is, why does the Stihl 180 chainsaw not start? Experts give the following recommendation on this matter: the first thing to do for those who have encountered a similar problem is to open and then close the lid located on the gas tank. There is another solution: take out the candle and let it dry. You can also create the effect of artificial ventilation for the combustion chamber. Most often, these recommendations are enough to bring the device back to working condition. However, this does not always help to restore the operation of the Stihl chainsaw.
- If there is a spark, but attempts to start the chainsaw do not lead to anything, then in this case you need check petrol supply, air filter, and then make sure the spark plug is working. Such manipulations must be done for the reason that most often such malfunctions are caused by contamination of the breather. And if a plug forms in it, then, naturally, a vacuum environment will be created in the gas tank, due to which the fuel will not flow. A similar problem can be solved quite simply, for which it is enough to remove the dirt using a needle.
- Some owners face this problem when the saw itself starts, but immediately starts to stall. Look for the cause of the saw not starting in the carburetor. Most likely, he managed to clog up and therefore does not allow the tool to work correctly.
- To make sure that the breather is not the cause of the malfunction, and it is in working order, you must first disconnect the fuel hose from the carburetor, then find out if there is a fuel leak.
- Keep in mind that it is natural for a properly functioning chainsaw to have dense and stable stream of gasoline. In addition, it is often possible to observe a situation when the Stihl 180 chainsaw does not start hot and immediately stalls at the same moment or after a while. Usually a similar malfunction is associated with a muffler. Most likely, it has accumulated a lot of deposits associated with long-term use of the tool, which is usually accompanied by the formation of exhaust.
- At the same time, the saw may stop starting if the tool chain is poorly lubricated. This can be facilitated by channels with a plug, or the reason should be sought in an oil pipe that has a leak.
- A serious problem can be leaks in the connecting pipes or at the installation site of the oil pump fittings.
- There are cases when the Stihl 180 chainsaw begins to stall due to a failed cylinder. To make sure whether this is really so, it is enough to conduct an inspection. If, as a result of the examination, you find irregularities and chips, then this is a clear sign of breakage.
The characteristics of this saw are a reason for the pride of the German manufacturer. In this case, the unit is a tool that is designed to perform a small amount of work. The tool is positioned for domestic use, which confirms the intensity of its use, which should not exceed 20 hours per month. Having such a unit at your disposal, it will not be difficult for you to maintain order in your garden, to prepare firewood for the winter, as well as to clear areas. At the same time, he will be able to help you in solving other problems, where there is no need to perform complex manipulations.
We determine the availability of fuel and its supply.
First you need to make sure that there is a fuel mixture in the tank of a chainsaw that does not want to start, and it regularly enters the carburetor. With a full tank, we check how the mixture is fed through the gas line. Disconnect the fuel system pipe from the carburetor and try to pump it up. In the case of a complete order, when pumping, gasoline will be supplied in jerks in accordance with the standards set by the manufacturer. Poor or no fuel supply can result from:
- The fuel supply channel is clogged;
- Clogged fuel filter.
Often the reason for a poor start of the chainsaw can be a tank that is too full. In this case, you should pay attention to the presence of smudges under the saw case cover. If present, see the connection of the gasoline feed pipe to the carburetor. Most often, it is squeezed out by pressure when the tank cap is screwed on, filled up to the very neck, which prevents the engine from starting.
The quality of the fuel mixture can also be one of the reasons why the chainsaw does not start. If, after completing the work, the remaining gasoline is not drained, and the tool is left for long-term storage (more than 2 weeks), then the processes of gum formation and polymerization of components will begin to occur inside the tank. What can cause carbon deposits on the piston, rings and cylinder liner. Therefore, always prepare the mixture only in the required amount before work.
Checking the condition of the fuel and air filters.
If everything is in order with the fuel quality, the chainsaw engine may not start due to clogged fuel and air filters. To diagnose these elements, it will be necessary to perform a number of manipulations associated with their dismantling.
For the fuel filter:
- Disconnect the gasoline supply channel from the carburetor;
- Pump up fuel.
If there is little or no pressure in the pipe, disconnect the filter. Before this, free the tank from the mixture and remove the filter element itself. Dismantling is done with a wire hook. A clogged replacement cartridge that causes a poor starting of the chainsaw engine can be cleaned, but it is best to replace it with a new one. When operating the tool in dusty conditions, it should be cleaned on a regular basis.
A clogged air filter can cause the chainsaw engine to run erratically, making it stalling or difficult to start. Dust and dirt deposited on the adsorbent material impedes the flow of air into the system, making the fuel mixture so rich that starting the tool will sometimes be difficult.
Checking the air filter is one of the first steps in finding the cause of a poor start.
Care must be taken when removing the air filter, as dust accumulated on the surface of the saw during operation can enter the carburetor. And this is fraught with more expensive repairs. After detaching the cartridge, thoroughly clean it from the accumulated dirt and rinse it with the addition of detergent. Dry the element and place it in place just as carefully.
Identification and elimination of obvious malfunctions of the chainsaw.
To determine the reason why the chainsaw does not start or stalls when starting, it is necessary to troubleshoot the tool. The essence of the procedure is to consistently inspect the condition and operation of the main working elements of the saw motor. At this stage, we check:
- Spark plug present;
- Fuel supply;
- Filter status;
- The operation of the breather of the stalling unit built into the fuel cap;
- Functioning of the outlet channel.

Checking the breather and cleaning it.
The breather is another element, from the improper operation of which the chainsaw may not start or stall during the sawing process. This element is located on the fuel tank cap in the area of the air hole. This is a kind of valve that prevents gasoline from flowing out and equalizes the air pressure required for the free flow of fuel into the carburetor.
If the breather is dirty, the working chainsaw stalls, and when it starts it refuses to start. The thing is that air stops flowing through the hole. As a result, a negative pressure (vacuum) is created inside the fuel tank, preventing the flow of gasoline to the carburetor.
Defining the problem is pretty straightforward. Disconnect the fuel hose from the carburetor and see what happens to the gasoline. If it flows out without hindrance in a good trickle, then everything is in order with the breather. If it is absent or it flows weakly and intermittently, then the reason is identified the breather is clogged with dirt. You can solve the problem by cleaning the air hole with a regular needle or a powerful jet of compressed air.
Checking the spark on the spark plug and eliminating the cause.
The first step in looking for reasons why your gasoline saw won’t start is to check the spark on the spark plug. There are many factors that affect the performance of this element. However, the main ones at the initial stage of instrument troubleshooting are:
- Incorrect carburetor adjustment;
- The presence of more than it should be, the amount of oil in gasoline;
- Clogged air filter.
All of them contribute to the formation of carbon deposits on the spark plug electrodes. In 50 cases out of 100, the saws do not start on a cold one due to the absence of a spark due to carbon deposits on the electrodes and their corrosion. As a result, the gap either decreases or increases.
Checking the spark plug with an idle chainsaw
It is quite easy to check for a spark. This will require:
- Remove the tip of the high-voltage wire;
- Unscrew the candle;
- Put the tip back on;
- Lean the candle with a skirt against the cylinder;
- Start with a starter.
If a good spark is observed between the electrodes at the time the chainsaw engine starts, then everything is in order with the ignition unit. If it is not there, then it is worth cleaning the element itself and checking the gap of the electrodes. If necessary, use a special probe to adjust the distance between the contacts.
There may be no spark on the spark plug for other reasons. Of the main faults affecting the poor start of the chainsaw and the unstable operation of the internal combustion engine at idle, from which the tool can stall, the following can be attributed:
- Overflow of the spark plug channel with fuel;
- Lack of contact between the high-voltage cradle and the tip of the candle;
- Failure of the ignition unit.
How to start a cold chainsaw if the candle channel is constantly flooding with gasoline? To eliminate the problem while starting the tool, you can use the following algorithm:
- Unscrew the candle with a special key;
- Wipe it with a clean and dry cloth;
- Dry for 2030 minutes;
- Remove carbon deposits with a file and adjust the gap between the electrodes;
- Drain the remaining fuel from the spark plug channel and dry it;
- Collect everything and try to start the mechanism.
If there is no spark with poor contact of the high-voltage cradle with the spark plug tip, check the connection. The check can be done using a conventional tester. If a defect is found and its elimination, the chainsaw should start without any problems.
If the check showed that the contact is reliable, and the saw will not start further, look for the cause in the ignition unit. As a rule, a faulty unit cannot be repaired or restored. It will require a complete replacement.
Finding reasons why your chainsaw won’t start
Amateur and professional chainsaws are complex devices. The service life of their two-stroke engines, components and assemblies has its limitations. For this reason, quite reliable and expensive tools, along with cheap Chinese units, periodically fail and refuse to start. The situation when the chainsaw does not start or stalls is not very pleasant and sometimes confuses the user. How to identify and correct a malfunction by returning the instrument to work.
- Identification and elimination of obvious malfunctions of the chainsaw.
- Checking the spark on the spark plug and eliminating the cause.
- We determine the availability of fuel and its supply.
- Checking the condition of the fuel and air filters.
- Checking the breather and cleaning it.
- Checking the outlet of the chainsaw.
- What if the chainsaw won’t start further?

Shtil chainsaw won’t start: reasons and solutions
First of all, it is worth noting the fact that the 180 chainsaw of this manufacturer is one of his best creations, but it also has its drawbacks. Actually, about which we will now talk.
- A fairly common problem is that the Stihl 180 chainsaw does not start and floods a candle. The reason for this is that the oil used to lubricate the chain starts to leak. Since time is merciless and simply breaks the tightness exactly in the place where the hose from the oil pump and the oil tank is actually connected. Naturally, this problem can be solved, but, given the design of this chainsaw, it will not be so easy to do this, since you simply have to completely disassemble the device in order, as they say, to get to the right place. It can be seen more clearly: https: //www.Youtube.com/watch? V = UOsYJBOVuwg
- Many are worried about this question: why does the Stihl 180 chainsaw not start? If you believe the experts, then in such a situation, you first need to open, and then close the lid that is on the gas tank. Or get out and dry the candle. Or try to ventilate the combustion chamber. In most cases, this kind of manipulation is enough to make the device work. But there are times when the Stihl chainsaw does not start, but there is a spark.
- In the above case, you need to make a direct checking the gas supply, air filter and the direct performance of the candle. Since the basis of this kind of breakdown is the breather, namely its pollution. Because when it is completely clogged, a kind of vacuum arises in the gas tank itself, which simply interferes with the fuel supply process. This issue is not difficult to solve, since all you need to do is clean it using a needle.
- There are also situations when the device, in principle started up, but immediately died out.
In order to exclude the saloon from damaged objects, it is necessary first of all to disconnect the fuel hose from the carburetor itself and actually check if fuel is leaking from it.
- You must remember that in the process of using your chainsaw correctly gasoline should flow out in a dense and stable stream. Also, it is not uncommon for the Stihl 180 chainsaw to not start up hot and actually stall after switching on or holds power for a rather short time. In this case, the problem of breakdown lies precisely in the muffler, which can be simply clogged with any deposits that arise through the operation of the device , and which settle during the exhaust process.
- Also, a fairly common cause of tool malfunction is insufficient lubrication of the device chain itself. The reason for this may be the channels that are simply clogged, or the reason is in the oil line that is leaking.
- Connecting pipes or the connections themselves in the area of the oil pump fittings can also leak.
- It happens that the Stihl 180 chainsaw does not start well due to cylinder that can be broken. But to determine its condition, a visual inspection is enough. But if even there you find the formation of irregularities and chips, then you can be sure that you have found the cause of the breakdown.
- If through verification you find that malfunction in the candle, then you simply need to turn it out, and then dry it directly. But it is worth noting that in no case should you pierce it, since you will simply spoil the part, and it will be unusable. You also need to drain excess fuel from it through a special hole.
Over, it may be that the expiration date of your candle has simply passed, in which case it is necessary to replace it. Therefore, it is a great advice that it is best to always have a new candle in stock or, best of all, a set. Then you can replace it at any time and actually understand whether it was the direct cause of the device breakdown. Over, a weak contact can also be the cause of a breakdown, which actually connects the high-voltage wire and the end of the candle. Also, the cause may be a breakdown of the ignition unit. It is worth noting the fact that in order to eliminate this kind of problem, it is necessary to replace the unit itself, since it cannot be repaired.
- Equally important is the concern of the owners of this model regarding systematic idling after the actual gasoline first tanks are empty. But if experts in this field are to be believed, they argue that this kind of situation does not pose any problem. But still, if this kind of process is repeated quite often, then you need to simply reduce the engine speed by using the carburetor screw.
- In addition, you can personally produce cleaning the muffler itself, since the cause of the malfunction may be in it. This manipulation is not difficult. A fairly common phenomenon of poor-quality tool operation is the carburetor.
It is important that if you even found the very cause of the instrument malfunction, this does not mean at all that you can eliminate it yourself. Since there are such breakdowns that can only be corrected by a specialist. If you have carried out direct manipulation regarding checking and changing the quality of the oil (see oil for the Stihl chainsaw), but, nevertheless, the chainsaw still refuses to start, in this case, you need to continue searching.
But if you fully performed all the manipulations prescribed above and did not miss a single nuance, but nevertheless the instrument has not yet been corrected, then in this case the problem lies in the group, which is called cylinder. But if you still could not bring your iron friend back to life, then simply take the chainsaw to a service center where your device will be repaired. Also, do not forget to take care of the engine to find out the ratio of gasoline and oil for chainsaws, read this article.
Stihl-180 does not start: reasons and remedies, why the chainsaw floods the candle, gasoline does not flow to the cold
Today the manufacturer Stihl occupies a leading position among other companies that produce equipment for agricultural and construction work. The products of this manufacturer are famous not only for their high level of quality, but also for the optimal pricing policy and power of its models. Probably, it is quite difficult to meet a person who does not have a chainsaw of this brand. This is one of the most famous world companies. But the fact that out of ten possible, six people definitely have them. This is not surprising, since Stihl chainsaws deliver power as well as graceful design. But unfortunately, such giants of technology sometimes fail and require some kind of repair. Let’s talk about the reasons why the Stihl chainsaw won’t start.
Briefly about the main
This model is the pride of the German manufacturer and is a direct tool intended for minor level work. It can be used no more than twenty hours a month. This excellent device will easily help you cope with the care of your garden, prepare firewood for the winter period of time (see how to cut down a tree), make cleared areas, and will also be an indispensable assistant in other areas, let’s say, simple manipulations.
We can say that these are a mini-model of chainsaws, since it has a small weighing about 3.9 kg, it does not have a large mass of both oil and fuel tanks. The manufacturer has equipped this device with a two-stroke engine with ample power for light work.
Over, it is quite quiet since during operation the noise level does not exceed 98 dB. So to better understand the level of loudness itself, just compare its noise with spoken speech, which has an indicator of 76 dB.
The power of this model is equal to 2.6 W. It’s worth noting that this is a fairly significant level of strength, given that it is not a professional chainsaw. The oil tank has a volume of only 0.145 liters, and the fuel tank 0.25 liters. The tire has a dimension of 350 mm and a pitch of 0.325 inches.
Stihl saw winding device
The basis of a plant of this kind of model, as well as all other chainsaws, is a carburetor. But since we are talking today about the Stihl 180 chainsaw, we will not deviate from the topic. So. The carburetor in this model has a single adjusting screw, that is, it is a kind of idle stroke adjustment screw. While the fully loaded jet is stationary.
In simple terms, we can say that it simply cannot be adjusted (see here), while the full load setting simply cannot be changed. It is important that the carburetor itself at the factory was configured in such a way that regardless of the actual conditions under which the chainsaw is operated directly, the air-fuel mixture is supplied to the engine itself.
