Mower Does Not Start Petrol Reasons

Why won’t the petrol trimmer start? Causes and their elimination

Recently, the gasoline trimmer has acquired the status of one of the main tools in the arsenal of summer residents. And this is not surprising, because a motorized scythe allows you to quickly put your personal plot in order. However, it sometimes happens that the trimmer does not start hot or even cold. In such situations, you have to independently determine the cause of the malfunction. Let’s figure out what to do if the trimmer won’t start. The reasons that most often lead to such troubles will be discussed below.

Diagnostics of the candle channel

What to do if the used fuel mixture is in good order, but the petrol trimmer still won’t start? The reasons for the failure of the mechanism may lie in the excessive moisture of the candle channel. To diagnose and fix the problem, you must do the following:

  • Unscrew the candle. Wipe it thoroughly and then dry it.
  • Drain excess fuel in the chamber through the appropriate plug hole.
  • Clean the old plug if there is carbon deposits on its surface. To cope with the task will allow the use of a regular ladies’ nail file or a file.
  • When installing the element in place, set a gap of 1 mm. To check the parameter, it is enough to place any coin in the gap.
  • Assemble the functional block back.
  • Try to start the trimmer.

It is recommended to dry the candle channel for at least half an hour. However, in no case should you resort to calcining its elements. After all, heating the spark plug can lead to its final damage. What to do if the function block was serviced in accordance with the above recommendations, but the trimmer does not start, there is still a spark? In this case, it is worth treating the threaded connection with gasoline. The latter does not need to be abundantly impregnated with fuel. It should only be slightly damp. Such actions should be taken to ensure ignition. After all, no matter how strong a spark the candle gives, in an absolutely dry chamber there will simply not be anything to ignite.

If even in this case the trimmer does not start, it is worth evaluating the quality of the contact between the high-voltage wire and the candle. In the absence of a spark (if there is a reliable connection between these elements), most likely, the problem is caused by a breakdown of the ignition unit. In this situation, you will have to turn to the services of wizards who will reinstall the node.

Troubleshooting strategy

Where to start troubleshooting if the trimmer won’t start? In situations where the tool stalls immediately after starting, it is worth inspecting the following components of the unit:

  • Fuel tank;
  • Spark plug;
  • Fuel and air filter;
  • Exhaust channel;
  • Breather.

It is the breakdown of the above locations that most often leads to the fact that the trimmer does not start well. Let’s look at how to eliminate such troubles.

Off-season petrol trimmer storage tips

When storing the trimmer, it is worth filling the gearbox with enough oil. Then you need to clean the air filter, partially disassemble, blow out and rinse the engine of the unit. After drying all mechanisms, the moving elements should be lubricated. To process the piston system with oils, you must first remove the spark plug. Then you need to move the piston to the extreme position, then pour a small amount of oil into the plug hole and rotate the crankshaft. If you do not plan to store the petrol trimmer in the off-season in the house, it is recommended to tightly wrap the engine of the unit with oiled rags. This will avoid the development of corrosion on the surface of important parts of the mechanism.

Filter check

Another common reason a trimmer won’t start is a blockage in the filter area. To confirm the guess, it is enough to dismantle the indicated block and try to start the unit without it. If the trimmer engine starts, most likely you will have to replace the air filter or at least thoroughly purge the old one. If there is heavy contamination on the surface of the filter element, a new mesh must be used. When resorting to such actions, do not leave the suction pipe completely without a filter. After all, haste in this case can lead to the need to repair the entire piston group of the engine unit.

Checking the fuel mixture

Let’s say your trimmer won’t start. In this case, the first step is to check whether there is enough fuel in the tank, and also to assess the quality of the fuel mixture. It is necessary to refuel the motorized unit with exclusively high-quality gasoline. It is recommended to use fuel with a grade not lower than AI-95. Filling the trimmer with fuel of unknown origin not purchased from a gas station can cause frequent tool malfunctions. This can cause damage to the piston-cylinder system. In this case, repairs often exceed the cost of the device itself.

Why won’t the petrol trimmer start? Improper preparation of the fuel mixture, which consists of oil and gasoline, can also lead to this. The proportions in which these components are connected are indicated by the manufacturers in the trimmer instruction manual. It is highly discouraged to prepare the fuel mixture in large volumes, that is, for the future. Indeed, with long-term savings, there is a loss of the defining properties of the substance. Therefore, if the trimmer does not start, it is worth draining the old fuel and using a freshly prepared fuel mixture.

What to do if your petrol lawnmower won’t start

The main thing in using any garden equipment (and equipment in general) is compliance with all operational requirements, as well as timely maintenance. Only under these conditions will the petrol lawn mower work properly and for a long time. However, unforeseen situations do happen, and one "fine" day the device may stop starting. Today we will find out why this happens and how you can fix this kind of problem.

Common breakdowns and how to fix them yourself

If the mower does not want to start, then first of all check if there is any gasoline in it. If not, top up to the required level. The fact is that if the device is idle for a long time, the gasoline is “exhausted” from it, therefore, it must be drained and replaced with a new one. Do this carefully so that fuel does not get on the engine (otherwise it may ignite).

By the way, if you are just planning to buy a gasoline lawn mower or any other garden equipment, we recommend visiting the site gardenmoto.Ru. There you will find a wide range of products at very reasonable prices. But back to the unwillingness of the device to start.

So, the next reason why a similar problem may arise is the incorrect position of the air damper when making the first start. Based on the air temperature, this damper either closes completely or rises to the middle position (if the temperature is 30 degrees). After that, it should be opened entirely.

We also recommend inspecting the air filter to see if it is dirty. To do this, turn on the mower and disconnect the cable from the spark plug. Remove the cover, remove the filter, wash it with gasoline and dry it thoroughly (or, alternatively, put a new one).

Finally, the last reason is a faulty candle (by the way, it may be just filled with gasoline). To find out, unscrew it, clean it and check for a spark. Next, close the choke and try to start the engine. If this does not work, you better trust an experienced professional.

As a result, we also recommend that you regularly study the lower part of the mower, as damage on it can be the reason that the engine will not start. That’s all, good luck!

Shtil chainsaw won’t start: reasons and solutions

First of all, it is worth noting the fact that the chainsaw 180 of this manufacturer is one of his best "creations", but it also has its drawbacks. Actually, which we will talk about now.

  • A fairly common problem is that the Stihl 180 chainsaw does not start and fills the candle. The reason for this is that the oil that is added 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: // 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 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 quite enough for the device to work. But there are times when the Stihl chainsaw does not start, but there is a spark.
  • In the above case, you need to directly check the supply of gasoline, the air filter and the direct performance of the spark plug. 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 correct operation of the chainsaw, gasoline should flow out in a dense and stable stream. It is also not uncommon for the Stihl 180 chainsaw to not start up hot and actually stall after switching on, or holds power for a fairly short time.In this case, the problem of breakdown lies precisely in the muffler, which can simply be clogged with any deposits that arise through the operation of the device , and which are deposited 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 channels that are simply clogged, or the reason is in the oil pipe 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 because of the cylinder, which 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, by checking, you find that the malfunction is 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 ruin 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, which actually connects the high-voltage wire and the end of the candle, can also be the cause of the breakdown. 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 excitement of the owners of this model regarding the systematic idle stroke 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 often enough, then you need to simply reduce the engine speed by using a carburetor screw.
  • In addition, you can personally clean 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.

    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 quality level, but also for the optimal pricing policy and power of its models. It is probably difficult enough 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 designed for a minor level of work. It can be used for no more than twenty hours a month. This wonderful device will easily help you cope with the care of your garden, prepare firewood for the winter period of time (see How to cut 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 mini-model of chainsaws, since it has a low weight, which is 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 enough power for light work.

    over, it is quite quiet since during operation the noise level does not exceed 98 dB. So that you 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 measures 350 mm and has a pitch of 0.325 inches.

    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 operated directly, the air-fuel mixture is supplied to the engine itself.

    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 a direct manipulation regarding checking and changing the quality of the oil (see Oil for Stihl chainsaw), but, nevertheless, the chainsaw still refuses to start, in this case, you must continue the 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 fixed, then the problem lies in the group, which is called the cylinder. 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.
