Gasoline does not flow into the carburetor of the lawn mowers
Lawn mowers carburetor device
The base of the carburetor for lawn mowers is a duralumin body. The diffuser (hole with inner contours) is located here. Air is blown through this hole. The flow rate of oxygen (air) depends on the cross-section (orifice) of the diffuser.
The diffuser is equipped with fuel channels. There is sucked in fuel when using a stream of air.
Outside the carburetor is installed:
- fuel pump;
- jet system;
- a system for adjusting the consistency of fuel with air;

Mesh filter. With this element, there are often only two obstacles:
To feel that you can find out the cause of the breakdown, the fuel filter cap is unscrewed to remove the strainer. If he just has dirt accumulated, then flushing in gasoline or blowing will help.
If there is visible damage to the mesh filter, it is imperative to install a new one. Damage also occurs on the fuel supply pipe (when performing repairs, they practice checking this element).

Stihl saw winding device
The basis of the plant of this kind of model, as well as all other chainsaws, is the 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 tuning screw, that is, it is a kind of idle travel 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 directly operated, the air-fuel mixture is supplied to the engine itself.
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 is enough to say that a person’s speech creates noise at a 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 l, the fuel tank is 0.25 l.
- Designed tire measures 350mm with 0.325 ” pitch.
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 companies in the world. 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.
Checking the carburetor and signs of need for adjustment
A properly working carburetor guarantees maximum efficiency of the chainsaw, that is, it is possible to develop full power with the most economical consumption of the fuel mixture. The adjustment of this unit is usually carried out by the manufacturer, but its design provides for the possibility of adjustment already during operation.
The fact that such a setting will have to be performed by the owner of the chainsaw is evidenced by:
- Strong vibrations or damage to the protective cap.
- CPG wear.
- Carburetor clogged.
- Inability to start the engine or its spontaneous stops after starting.
- Increased fuel consumption and exhaust emissions while decreasing engine power.
Chainsaw carburetor adjustment is carried out in strict accordance with the manufacturer’s instructions using three special screws that are responsible for the maximum (“M”) and minimum (“L”) revolutions, as well as idle (“T”). In order to exclude unwanted intervention by an inexperienced user in the operation of the carburetor, some manufacturers install only one idle screw.
It is important that if you even found the very cause of the instrument malfunction, this does not mean at all that you will be able to eliminate it yourself. Since there are such breakdowns that can only be corrected by a specialist. If you carried out a 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 must continue to search.
But if you fully performed all the manipulations prescribed above and did not miss a single nuance, but nevertheless the tool has not yet been corrected, then in this case the problem lies in the group, which is called the cylinder one. But if you still could not “bring back to life” your iron friend, 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.
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 devoid of disadvantages. 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 fills 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 joins 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 in this regard: the first thing to do for those who are faced with a similar problem is to open and then close the lid located on the gas tank. There is another solution. you need to remove 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 to check the supply of gasoline, the air filter, and then make sure that the spark plug is working. Such manipulations must be done for the reason that most often this kind of malfunction is 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, because of which the fuel will not flow. A similar problem can be solved quite simply, for which it is enough to remove dirt using a needle.
- Some owners face this problem when the saw itself starts, but immediately starts to stall. Look for the reason that the saw will not start should be in the carburetor. Most likely, he managed to get clogged 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, and then find out if there is a fuel leak.
- Keep in mind that it is natural for a properly functioning chainsaw to have a strong and stable jet 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 operation 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 that have a plug, or the reason should be looked for 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.
