Petrol Trimmer Worked And Stalled
Gas mowers and trimmers are very convenient, compact and maneuverable, suitable for work in any country house. They cope with grass in areas with different terrain and different sizes. Especially advantageous is their use in narrow, inaccessible places for a lawn mower. In addition, they are cheaper and easier to maintain than a lawn mower.

Gas trimmer: purpose of the tool in the country
The lawn trimmer is, in fact, a scythe for grass on gasoline. It is used for mowing decorative grass (leveling, cutting), for mowing weeds, for mowing grass on hay.
The trimmer does this quickly and accurately, in addition, it is lightweight and easy to maintain and does not require large storage space. The main thing that distinguishes the trimmer from a lawn mower.
With a trimmer you can not only cut grass and herbaceous plants, it perfectly cuts not thick (2.5-3 cm in diameter) branches of trees and shrubs. So it replaces the secateurs in the garden.
Types of trimmers on a gasoline engine
Consider the different types of gasoline trimmers and find out what kind of work is best suited for each of them.
Household
Used for mowing weeds and grass in adjacent areas. This is a lightweight tool with a curved handle with a power of 1 horsepower or a little more. Such trimmers are suitable for small volumes of work or infrequent mowing, haircuts.
When purchasing a household tool, you need to know how to use a grass trimmer. It needs to rest every 20-25 minutes of work, otherwise it may fail. But at the same time, the household trimmer has a moderate gas mileage and excellent maneuverability.
Professional
Their power is higher. 2-3 liters. S., respectively, and gasoline for a professional trimmer is consumed more. Such a trimmer performs a much larger amount of work and has a knife in the configuration, that is, shears both grass, and thin branches, shrubs.
It is also equipped with a shoulder strap and anti-vibration system. But also at work it requires rest every 30 minutes and cleaning the cutting part of the grass.
Universal
They are similar to professional ones, but they can also trim the lawns, that is, their trimmed canvas will be homogeneous, even and beautiful.
Lawn mowers
Not only grasses, branches and shrubs mow, but even young trees can cut. They have a capacity of over 3 liters. With. They can work without interruption for several hours in large areas.
How to choose a gas trimmer for a summer residence, selection criteria
Before choosing a gas trimmer, you need to at least briefly know the main parameters of the tool. The key to choosing a gas trimmer will be how often you plan to use it and what area it is intended for.
Based on this, the best gas trimmer for your particular site is selected according to the power and performance of each individual model.
Type and engine power
The best gas trimmers do not have to have the greatest power. If you have a small lawn. The most powerful trimmer is not required for her. A good medium power gas trimmer is fine. But if the cultivated area is large and there is a need to work on it for 6-7 hours a day, then you need a more powerful trimmer.
By the type of suspension, trimmers are straps. The best option for infrequent use, and trimmers with a knapsack suspension. These are best taken with a constant, almost daily load on the tool.
By type of drive, gas trimmers come with a straight shaft or with a metal cable. It is better to take a tool driven by a direct shaft. They are more wear resistant. By type of engine, gas trimmers are divided into two and four-cycle ones.
The former are filled with oil already mixed with gasoline, the latter have separate compartments for oil and gasoline. Push-pulls are considered more noisy, and their lifespan is often shorter. And four-stroke ones are more durable, more expensive to maintain and repair, but at the same time they work a little quieter.
The engine can be located in the upper or lower position. The ones located at the top are preferable. They are more convenient in operation, better cooled, more protected from clogging with grass and debris, and they, as a rule, have more power.
Knife and fishing line for trimmer
The line in the trimmer is used only for mowing grass. According to the type of pattern, several types of fishing line are distinguished:
- In the shape of an asterisk. For green decorative lawn or young grass;
- In the shape of a square. For tall grass with thick stems;
- In the shape of a circle. Universal view suitable for both lawn and woody and dry grass stems, leaves.
For cutting branches, cutting shrubs will need a knife. There are models equipped only with fishing line, and there are models with fishing line and with knives.
Weight and type of petrol trimmer handle
By the type of rod (handle), the trimmers come with a curved handle for small loads or with a straight one. For larger loads. The weight of the trimmer, as a rule, does not affect the operation of the instrument in any way, it matters to the person who works with it. If it’s a man, then you can take a heavier model, if a woman, then it’s easier.
When choosing an instrument by weight, you need to take into account the size of the trimmer’s gas tank. The larger it is, the heavier the trimmed trimmer will be (on average 0.6-1.5 kg).
Additional devices
Before choosing a trimmer for a lawn, study all the possibilities of each model. Some of them are endowed with additional useful functions. It can be a snow nozzle, anti-vibration system. For the convenience of hands, quick start of the trimmer with a decompression device, which increases the tool life.
Advantages and disadvantages of a gas trimmer in the garden
Advantages include mobility, versatility, and tool performance. Disadvantages. Not always a reasonable price, especially for multifunction mowers, and the noise of a working trimmer, even for models with reduced noise.
But, on the other hand, the tool has good power, performance, and besides, a gas trimmer can work in any weather (after rain, for example).
That’s all, how to choose a trimmer for a summer house or home. We want to decide and choose the trimmer that is suitable for your site, lawn or garden!
Caring for a personal plot, summer residents periodically encounter the fact that the lawn mowing does not start. There are many reasons for tool failure. For the correct diagnosis of the problem, the owner of the unit useful at the cottage needs to know the device and the principle of operation of its individual parts.

Where to start diagnosing lawn mowers
If the lawn mowing does not start or immediately stalls after start-up, it is necessary to check all the main components and assemblies in sequence. The verification algorithm is as follows:
- Fuel tank (fuel quality);
- Candle and candle channel;
- Air filter;
- Fuel filter;
- Breather;
- Exhaust channel.
These nodes are most often the source of major problems that can be fixed after a thorough inspection.
Checking the fuel mixture
Before starting the engine of the gas spit, check the availability and quality of the fuel mixture. Do not save, do not be greedy and do not be clever in this matter. Repair or replacement of the piston group will cost you too much (sometimes up to 70% of the cost of a new tool). It is necessary to prepare the oil-fuel mixture strictly according to the instructions. Calculate its quantity from real needs. Excess gasoline remaining after work over time loses its quality.
We diagnose a candle and a candle channel
If the quality of the fuel mixture is not in doubt, and the lawn mower stalls at start-up, then a filled candle may become the cause. Here, for repair, an ordinary candle key (probably every motorist has it) and a spare candle are suitable.
- We twist the candle and wipe it;
- Dry it thoroughly (do not calcine);
- The excess fuel in the chamber is drained through the spark plug hole and dried;
- We clear an old candle from a deposit by means of a file or a lady’s file;
- We set a gap with a distance of 1 mm (you can check with any coin);
- We return everything to its place and try to start a trimmer.
If the candle is working, the nest where it is completely dry and the lawn mower does not want to start, we lubricate the threaded connection with gasoline. It should be slightly moistened. No matter how wonderful a spark a candle gives out, there is simply nothing to light up in a dry chamber.
If the trimmer motor still does not start, a cause such as the absence of a spark due to poor contact between the spark plugs and the high-voltage wire should be excluded. If the connection is high-quality, but there is still no spark, most likely, your ignition unit has “flown”. Here you can’t do without a master, because the part is not being repaired, but sold as a single unit.
Diagnostics of lawn mowing filters
Another reason that the gas braid stalls may be an air filter. To exclude it, try to remove the filter and start the trimmer without it. If possible, then you will have to change the air filter to a new one, or at least blow out and thoroughly clean the old one.
A gas trimmer may not start up due to contamination of the fuel filter. This is the next step in our algorithm. Here we check the condition of the filter element and, if necessary, replace it with a new one. When replacing, try not to leave the suction pipe completely without a filter, this is prohibited by any operating instructions. Haste can result in repair of the engine piston group.
Breather and exhaust channel
Often, “gentle” branded lawn mowers do not start and stall due to contamination of the breather. The main function of this element is to equalize the pressure in the gas tank. If this unit becomes clogged, a vacuum is created in the tank, which prevents the fuel supply. You can fix the problem by cleaning the breather. You can use a regular needle for cleaning.
Normal operation of the braids with internal combustion engines may be impaired due to the ingress of dirt into the exhaust channel or clogging of the silencer mesh. There is such a problem on older models. You can solve the problem by traditional cleaning and removal of the anti-spark mesh.
Complex causes of lawn mowing failure
If the step-by-step algorithm for troubleshooting does not give a result, and your braid still does not start or stalls, it is worth examining the carburetor and the engine itself. A clogged carburetor can be one of the reasons for unstable tool operation. Three main problems can be distinguished here:
- Clogged channels or jets. All this is cleaned with special washes or purged with a powerful jet of compressed air from the compressor. Do not use needles and wire, as passage sections may be damaged;
- Worn carburetor gasket. Output. Replacement of failed gaskets;
- Violation of tightness. To check this indicator, you can use an ordinary household tonometer, replacing a manometer with a suitable one. Keep track of the readings: if they do not change, everything is fine, and if the pressure starts to fall, 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 gas trimmer may not start due to wear on the piston group. If chips, scratches, or nicks are found on the piston or cylinder, they should be replaced. Piston rings are subject to mandatory inspection. A slight piston loophole while rocking the connecting rod indicates that it is time to change the rings. This procedure is best entrusted to service center specialists.
Rules for the operation and storage of lawn mowers
In order for the lawn mowing to continue well, you need to provide it with good storage and operating conditions:
- During operation, carefully monitor the cooling system, carefully and timely clean the channels in the housing, as well as the fins of the starter;
- If necessary, use solvents, kerosene and other detergents for cleaning;
- Do not clean the tool “hot”. Let it cool;
- Strictly follow the requirements of the instruction regarding the operating mode, otherwise you may overheat the engine;
- If you do not plan to use the lawn mower in the next month, the fuel mixture must be drained from it, because over time it breaks up into heavy fractions that will uniquely clog the carburetor channels;
- After draining the fuel, let the trimmer idle until it dies, this will help to completely remove the remains of the working mixture.
Before winter storage, follow these steps:
- Completely disassemble the braid, rinse and clean all the details that you can;
- Inspect the parts for damage, if necessary, eliminate distortions, gusts, bends and any other malfunctions;
- Pour enough oil into the gearbox and clean the air filter;
- You can partially disassemble the motor, flush, blow and grease all moving parts;
- In order to lubricate the piston, you need to unscrew the candle, raise the piston to the dead center with the starter, pour a little oil into the spark plug hole and rotate the crankshaft a couple of times;
- If you are not keeping the lawn mowing house, wind the engine with an oiled rag.
