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 the 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.

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.

Gasoline trimmer won’t start: causes and remedies

Given the specifics of using gasoline trimmers, their owners often have to deal with certain problems. One common problem is that the lawn mower won’t start or pick up steam. For the fastest and most effective elimination of such a problem, you should have an idea of ​​the main causes of possible malfunctions.

Breather cleaning

Often, the engine of branded trim models stalls as a result of a clogged breather. The main task of this component is to equalize 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.

Wet spark plug on the gas trimmer. Flooded engine

Surely many who use small motorized equipment know what a “flooded” spark plug on an engine is and what unpleasant situations arise because of this. Very often, using newly acquired equipment, many do not check the condition of the spark plug electrodes after updating the fuel and lubricants, but remember this only when the first malfunctions appear.

Breather and exhaust port

Often, “gentle” branded lawn mowers will not start and stall due to a dirty breather. The main function of this element is to equalize the pressure in the gas tank. When this unit becomes clogged, a vacuum is created in the tank, which prevents the supply of fuel. You can eliminate the malfunction by cleaning the breather. You can use a regular needle for cleaning.

Normal operation of streamers with internal combustion engines can be disrupted due to the ingress of dirt into the exhaust duct or clogging of the muffler mesh. There is such a problem on older generation models. The issue can be resolved by traditional cleaning and removal of the anti-spark grid.

complex reasons for lawn mowers failure

If the step-by-step troubleshooting algorithm does not work, and your scythe still does not start or stalls, it is worth inspecting the carburetor and the engine itself. A clogged carburetor can be one of the reasons for erratic tool performance. There are three main problems here:

  • Clogged ducts or nozzles. All this is cleaned by special washes or blown by a powerful jet of compressed air from the compressor. Do not use needles and wires, as the bore may be damaged;
  • Worn carburetor gasket. Exit. replacement of a failed gasket;
  • Violation of tightness. To check this indicator, you can use an ordinary household tonometer, replacing it with a suitable pressure gauge. Watch the readings: if they do not change, everything is fine, and if the pressure starts to drop, then some part of the carburetor is faulty. We’ll have to find it and replace it with a new one.

If everything is in order with the carburetor, then the petrol trimmer may not start due to wear of the piston group. If chips, scratches or scuffs are found on the piston or cylinder, they should be replaced. Piston rings are subject to mandatory checks. A small backlash of the piston when rocking the connecting rod indicates that it is time to change the rings. This procedure is best entrusted to the specialists of the service center.

Lawnmower won’t start after winter: reasons and solutions

Many owners of modern models of gasoline tools are faced with such a problem as the complete lack of functionality of the unit after wintering. If the lawn mower does not start, the first step is to perform a comprehensive maintenance on the petrol trimmer. To do this, you need to remove the fuel system and disassemble the carburetor of the lawn mowers, thoroughly cleaning, rinsing and blowing air through each unit.

It should be noted that after winter, as a result of long-term storage, the diluted fuel mixture loses its basic characteristics, which also leads to the impossibility of starting the lawn mowers. The use of an updated fuel composition, in this case, eliminates the problem.

A typical malfunction is the absence of a spark, as a result of which it is necessary to check the contacts and the correctness of the gap between them. When there is a spark, but the tool still does not want to function, the valve, which is responsible for air entering the fuel tank, should be inspected. If it becomes clogged, cleaning is required. The reason that the lawn mower will not start may be hidden in the fuel filter, which needs to be cleaned and re-started the unit.

When you start the mower on a cold one, do not step on the gas. Tilt the tool so that the air filter is in the correct position and press the fuel suction button several times, fixing the options switch lever to the “start” position. Then pull the starter cord 6-7 times until the engine starts to function, after which, after waiting 5-8 seconds, turn off the starting system.

Today, there are many video clips on the Internet, in which the main causes of malfunctions of various models of lawn mowers after winter are considered in detail and the correct ways to eliminate them are proposed.

The petrol trimmer will not start. floods the candle / candle is always wet

Among the many reasons for which the trimmer will not start, it is the filled spark plugs that are considered the most common. According to statistics, every second owner of a tool faces a similar problem. In most cases, the candle is always wet for the following reasons:

  • Accumulation of large amounts of carbon deposits on the component.
  • Incorrect installation of the spare part.
  • Excessive supply of fuel mixture by injectors to the combustion chamber.

When the gasoline trimmer does not start due to the fact that the candle is constantly being poured, the user needs to eliminate the excess fuel mixture, thoroughly clean all the components involved in this process, and then blow out the candle, giving time for everything to dry.

Regardless of whether you are the owner of a budget Chinese-made gasoline tool or use expensive models from a brand such as Husqvarna, cleaning the lawn mower plug is carried out in the following sequence:

  • Turn the tool over, and run the starter until the excess fuel mixture is completely discharged.
  • Dismantle, blow out and clean the candle, leaving it to dry for 40 minutes.
  • A completely dry spare part is put back.
  • An attempt to launch a tool, and on a hot.

By following the above steps, you will be able to effectively troubleshoot faults caused by flooding the candle.

Why doesn’t the lawnmower start hot?

It often happens that the lawn mower does not start up hot. In this regard, the question “why?” Is quite logical. Mostly, the cause of such a malfunction can be associated with the following technical components of the tool:

  • Fuel tank.
  • Exhaust channel.
  • Breather.
  • Trimmer starter.

One of the common breakdowns that lead to the fact that the petrol trimmer does not start hot is the presence of a blockage in the area of ​​the air filter. Improper preparation of the fuel mixture, as well as its quality, also initiate a malfunction in the unit. Often the reason a 4-stroke lawnmower doesn’t want to start is if the candle channel is too wet.

The stable operation of the tool can also be impaired due to the accumulation of dirt in the exhaust channel or the accumulation of large amounts of debris on the muffler mesh.

What to do if the petrol trimmer won’t start

A long seasonal break in work, violation of storage rules and non-compliance with operating standards, lack of regular maintenance lead to the fact that the petrol trimmer does not start. In this case, the first step is to make sure that the fuel mixture is available and its quality.

For petrol trimmers from manufacturers such as Stihl or Husqvarna, prepare the oil / fuel mixture as indicated using the appropriate brand of oil. After verifying that the fuel mixture is flawless, but the tool still does not start, check for a spark, which can often be missing from a flooded spark plug. If the spark plug is dry, the connection is of good quality, but there is no spark, most likely the ignition unit is out of order.

What if the above points are in order, but the Sturm lawn mower or Stihl petrol trimmer does not start? It is necessary to diagnose the gasoline and fuel filter, as well as carefully examine the carburetor for the likelihood of piston group wear.

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 an oiled rag. This will avoid the development of corrosion on the surface of important parts of the mechanism.

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 old spark 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 moist. Such actions should be taken to ensure ignition. After all, no matter how strong a 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 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.

How to prevent sudden breakage during trimmer operation?

In order for the unit to always be in a functional state, it is worth following a few simple rules:

  • Conduct a timely, regular technical inspection of the main mechanical components of the device.
  • Fill the trimmer with only fresh fuel, the quality and origin of which is beyond doubt.
  • After each use of the tool, check whether oxides and carbon deposits have formed on the surface of the ignition system.
  • Avoid heavy load on the trimmer during work.

In order for the unit to remain in working order, it is necessary to properly prepare it for storage in the winter. First of all, you should completely disassemble the instrument, then flush and clean the constituent elements. It is also important to inspect functional blocks for damage, if necessary, eliminating deformation of parts, all kinds of distortions, gusts of materials.

Filter check

Another common reason the trimmer won’t start is if there 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 dirt 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, 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 failures. 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 a 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.

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.
