Trimmer Won’T Start Candle Wet Spark Present

Lawnmower won’t start: causes and remedies

Diagnostics of the reasons why the lawn mower won’t start. Quick return to life of Chinese and domestic two-stroke internal combustion lawn mower.

It happens that a two-stroke motor does NOT show even a flash in the cylinder, but it happens. Grabs, and then stalls. Do NOT be sad, this Chinese consumer goods can be repaired right on the knee with a minimum of tools.

Before starting diagnostics, you need to make sure that the motor rotates with little resistance. If there is compression in it, it means that further is useless, and you need to change the piston (there is nothing complicated about this either, everything is like a designer).

Exhaust channel

The reason that the trimmer has significantly lost power, and when trying to increase engine speed, it picks up slowly, often is the clogging of the exhaust channel, through which the exhaust gases come out of the combustion chamber.

It is necessary to remove the muffler so that the burn overshoots inside the cylinder. Next, clean the exhaust channel from carbon deposits.

This must be done very carefully, do not allow carbon deposits to enter the combustion chamber.

After this procedure, the weak power of the unit and a slow increase in the speed of rotation of the mowing head will no longer upset you.

Second. Carburetor

It is not necessary to disassemble the unit right away, especially if the engine stalls after starting or does not keep idling. Try changing the fuel first, it may have an excess of oil. You can inject the purifier into the air filter, give the motor a little “fuck up” at maximum speed.

Next, we go in order. Air filter, fuel filter (it can be outside and in the tank), fuel pump button, hose integrity. Gas tank cap. The ventilation valve may be clogged, the motor simply does not pump gasoline. Purge everything. And it will work!

Required. Look at the connection of the carburetor to the intake manifold! Elsi sucks air there and there is no tightness. Eliminate!

Dispensing needle hangs up. Also a problem in some models. It is enough to push it down, or remove and grind it with velvet.

You can pull off the hose from the carburetor, see if the fuel goes to it when pumping. It is clear that often for checking you need to remove the plastic sheathing, break your fingers into the latches, but anyway, sooner or later you will have to climb there.

Reasons why a new trimmer won’t start

Startup difficulties arise Not only in well-worn lawn mowers, but also in brand new ones. In this situation, there is only one way out. Listen to the advice of our experts and benefit from their practical experience!

Grisha participant of FORUMHOUSE

The reasons why a new gasoline trimmer does not start is eliminated by the instruction for the lawn mowers plant from members of the forum, which sounds like this:

  • Switch on ignition.
  • Pump up fuel with a silicone button (primer) located on the bottom of the carburetor. Pressing must be done as much (or a little more) as written in the instructions, usually about 8-10.
  • Close air damper.
  • Lock the throttle lever with a stop button at high rpm.
  • Turf the starter handle 2-3 times. The engine should “grab”.

If the engine “grabs” and stalled, then you need to move the choke to the 1/2 position and try to start the engine again. If the engine starts, then we release the gas and move the air damper to the “open” position. The trimmer is easy to start. Getting started.

When performing manipulations on pumping fuel, do not be afraid to pour it over. If this happened and the candle was “filled in”, then there is no need to unscrew it, it is enough to move the air damper to the “open” position and, while holding full throttle, simultaneously turn the engine with a starter 2-4 times. After that, you can start the engine and start mowing the grass, and not being afraid that it will stall.

See the trimmer’s instruction manual for the continuous running time of the lawn mower. On average, oblique 15-20 minutes, after which you need to drown the trimmer and let it cool for 3-5 minutes. Also, the duration of continuous operation is significantly influenced by the weather and operating conditions. In the heat, when mowing tall grass, thickets of weeds, under heavy load, the trimmer overheats faster, does not work and hardly starts after a break.

Lawn Mower Does Not Start After Winter

In such cases, the unit must be serviced. Remove the fuel system, including filters (air, fuel), disassemble the carburetor, clean and rinse each unit. Blow out the filters with air. Pay attention to fuel quality and octane number.

It should be noted that the products of such well-known companies as STIHL, Husgvarna and other brands will not run on cheap, low-octane gasoline. For them, fuel from the AI ​​brand is suitable. 92 and higher from car gas stations and then, from well-recommended ones, since there is also bad gasoline at gas stations. Here are the applications of high-octane and high-quality gasoline, it will depend on how long the lawn mower will be used and how long it will last.

It is necessary to take into account one more fact that with a long storage of a diluted fuel mixture, working qualities fall into it, which also leads to the consequences in which the lawn mower does not start. Therefore, it should be diluted in portions, that is, the amount of the mixture that is produced at a time. The operating instructions clearly describe and explain the mixing ratio of gasoline and oil. Strict observance of the correct proportions will at least save you from several questions, why the lawn mower does not start and what to do in such cases.

We carry out diagnostics of the candle and candle channel

If the quality of the fuel mixture is not in doubt, and the lawn mower stalls when starting, then a flooded candle may be a prerequisite. Here, an ordinary spark plug wrench is suitable for repairs (every motorist probably has) and a spare candle.

  • We unscrew the candle and wipe it;
  • Dry it thoroughly (not cost if ignited)
  • Excess fuel in the chamber Drain through the spark plug hole and dry it;
  • We clean the old candle from carbon deposits using a file or a lady’s file;
  • We set a gap with a distance of 1 mm (you can check with any coin)
  • Putting everything back in place and trying to start the trimmer.

Dries the channel for at least 30-40 minutes. Otherwise, there is a risk of re-filling and a new candle.

If the candle is working, the socket where it is located is completely dry, and the lawn mower does not want to start, lubricate the threaded connection with gasoline. It should be slightly damp. No matter how wonderful a spark the candle gives out, there is simply nothing to light up in a dry chamber.

If the trimmer motor still does not start, you should exclude such a reason as the absence of a spark due to weak contact between the spark plugs and the high-voltage wire. If the connection is of good quality, but there is still no spark, most likely your ignition unit has “flown”. Here you will NOT be able to do without a master, since the part is not repaired, but sold as a single unit.

Cleaning the breather

Often, the engine of branded trim models stalls as a result of a clogged breather. The main task of the specified component. Equalizing the pressure in the fuel tank. In case of contamination of the unit, a vacuum is formed here, which significantly complicates the supply of fuel. The problem can be eliminated by cleaning the breather with a regular sewing needle.

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 moistening 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 should be done if the maintenance of the functional unit was performed in accordance with the above recommendations, but the trimmer does not start, there is a spark? In this case, it is worth treating the threaded connection with gasoline. The latter does not need to be saturated with fuel abundantly. It should only be slightly damp. Such actions should be taken to ensure ignition. After all, no matter how strong the spark the candle gives, there will simply be nothing to ignite in an absolutely dry chamber.

If, even in this case, the trimmer does not start, it is worth assessing 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 the indicated elements), the problem is most likely caused by a breakdown of the ignition unit. In this situation, you will have to turn to the services of the wizards who will reinstall the node.

Outlet duct diagnostics

Stable trimmer performance can be compromised by build-up of dirt in the exhaust duct or blockage in the muffler mesh. This problem most often occurs during the operation of older generation trimmer models. The issue is being solved by dismantling the anti-spark grid and cleaning it.

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.

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, the grade of which is 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.

Trimmer Won'T Start Candle Wet Spark Present

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. Preparing a fuel mixture is highly discouraged 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.

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. I dried all the 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 spark 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 the principal components of the mechanism.

How to eliminate the reasons why the device does NOT start

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 in the Stihl 180 chainsaw, there will be NO departure 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.

Stihl-180 Will not start: reasons and remedies, why the chainsaw fills the candle, and gasoline does not flow to the cold

Today the manufacturer Stihl takes a leading place 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. 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 in six people they are for sure. 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.

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, which can only be fixed by a specialist. If you carried out direct manipulations regarding checking and replacing 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 is still NOT fixed, then in this case 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. Also Do not forget to take care of the engine to find out the ratio of gasoline and oil for chainsaws, read this article.

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 as 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 is worth noting that this is a sufficiently Substantial level of strength, taking into account that She 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. 0.325 inches.

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, in which we will now talk.

  • 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 only be solved, 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 need to first 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. It is not difficult to solve this issue, since all you need to do is clean it by 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 whether 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. 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. , and which settle during the exhaust process.
  • Also, a fairly common prerequisite for tool malfunction is insufficient lubrication of the device chain itself. The reason for this may be the channels, which are simply clogged, or the reason in the oil line 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 damaged. 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 Unscrew it, and then directly dry it. But it is worth noting that in no case can you pierce it, since you 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 the actual concepts, 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 a prerequisite for breakdown. Also, a prerequisite 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 of systematic idling after the actual first gasoline 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 complicated. A fairly common phenomenon of poor-quality tool operation is the carburetor.
