Trimmer Does Not Start Causes And Remedies
Problem with starter and ignition switch
The battery may be charged and the high voltage wires are fine, but you still cannot start the engine. Then the cause of the malfunction should be looked for already at the ignition switch or starter.
To check if the ignition switch is working properly, insert the key into the ignition lock and turn it to the second position. If the red lights on the dashboard do not light up, then the ignition switch may be faulty. You can check in another way. At the time of an attempt to start the engine, turn on the headlights, if they start to fade, then the ignition is in working order. A malfunction of the ignition switch is eliminated in most cases by replacing the switch.
Corrosion and dirt not only damage the wires on the battery, but also the starter. You will need a tester and assistant to test the starter’s performance. The electrical tester is connected to the wire that powers the car’s starter. At this point, the assistant should try to start the engine. If the tester shows that there is electric current on the wire, but the starter does not crank, then this problem can be solved by replacing the starter. Attention! Do not forget about the precautions, do not touch the wires and other parts of the engine with bare hands. It is best to carry out this procedure with dielectric gloves.
There are times when the starter turns, the car will not start. What to do in this situation? To answer the difficult and trivial question of why the car won’t start, you need to check other components of the car. Lack of spark is another reason why the engine refuses to start. Checking the spark plugs should worry you in the last place, first you need to deal with the ignition coil.
The car will not start: possible causes and methods of their elimination
Nowadays, a car is not a luxury, but a means of transportation. Every driver faced a problem when his iron horse refused to ride. This is the most unpleasant situation due to which you can be late for work, miss a vacation with friends, or other important event. So what if the car won’t start? For starters, do not panic, many problems can be solved on your own and without visiting a car service. So, if the car does not start, you need to look for the reasons under the hood.
Ignition
So, if all of the above is in good working order, check the ignition. First you need to test the ignition coil. It is checked with a multimeter. If there is no such device, then you can call the nearest car service.
It happens that moisture accumulates in the ignition distribution cover, this can be the reason why the engine does not start. The cover must be removed and checked for moisture. Any moisture or condensation that appears must be removed with a dry cloth. Once you had to remove the cover, you should check it for cracks. A cracked cover should be replaced with a new one.
The wires to the ignition coil can be damaged or an electric shock. Bring the tester to the insulation of the wires. Good wires will not conduct current through the insulation. If the tester shows that the wires are faulty, you will have to buy new ones.
The engine does not start in cold weather
Starting a car in severe frost is difficult, but not hopeless. If the temperature outside is 15 C and lower, then any battery loses 50% of its capacity, this is another problem why the car does not start well. To wake up the car, you must turn on the high beam for 10-15 seconds. This will allow the electrolyte in the battery to warm up for additional energy.
Attention! Never turn the starter for more than 5 seconds. Otherwise, there is a chance to completely drain the battery or fill the candles, which is unacceptable at low temperatures. If the car is in good condition, then from the 2-3rd attempt everything will work out, and your car will start.
It happens that the battery runs out completely. This can be understood if the car stalled and will not start. In this case, you will need a cigarette lighter. If the car has an injection engine, it will be more difficult to light a cigarette due to the large amount of electronics. You can also light a cigarette from another car when the engine is running. The main thing is not to confuse polarity and sequence. However, if you made a mistake and mixed up the signs, run faster for a new battery.
After connecting to the donor machine, you need to wait 10-15 minutes for your battery to charge. Then we disconnect from the car and try to start. If the engine is running, give it a couple of minutes, otherwise it will stall.
Remember that starting the engine in subzero temperatures equals 500 km. Take care of your car.
Fuel system problems
Car won’t start? Is the starter motor running at full power, but the engine still won’t start? Then the problem should be looked for in the fuel supply. Electronic fuel delivery is often used on modern cars. The problem is that it will be difficult to diagnose on your own. Diagnostic equipment is expensive and you need to go to a car service. But there are signs by which you can understand what kind of malfunction in the fuel system is, thereby you will save money on diagnostics.
The very first thing you should do is check all electrical wires under the hood. It will take a lot of time, but it’s better than paying a lot of money for diagnostics. Each injector that supplies fuel to the system has its own separate wire. Check all wires with a tester, and also pay attention to the insulation.
Car won’t start? The cause of the malfunction when starting the engine may be in the operation of the fuel pump. You can check its performance only on special equipment, which not every driver has. You can try to find out the reason by checking the voltage on the positive wire of the fuel pump. It may be missing due to a faulty fuse. If the fuse is working, and there is no voltage in the wire, then this problem can be solved by replacing the fuel pump motor relay.
A working fuel pump does not mean that the fuel system is in order. The filter may become clogged and not deliver fuel. To prevent this from happening, it should be changed every 20,000 km. You can replace all these parts yourself. Why won’t the car start if the entire fuel system is in good condition? We do not despair and look for the problem further.
Spark plug
Candles are intended for ignition of fuel-air mixtures. They are found in different types: spark, incandescent, semiconductor and others. If your car won’t start, then a long rotation of the starter will lead to filling the candles. After which they will need to be changed. Otherwise, working with flooded candles will harm other parts of your car.
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 mowers.
It happens that a two-stroke motor does not even show a flash in the cylinder, but sometimes it catches it and immediately stalls. Do not be sad, this Chinese commodity can be repaired right on the knee using a minimum of tools.
Before starting diagnostics, you need to make sure that the motor rotates with little resistance. If there is no compression in it, then further is useless, and you need to change the piston (there is nothing complicated about this either, everything is like a designer).
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 the air filter, the fuel filter (it can be outside and in the tank), the fuel pumping button, the integrity of the hoses. The gas tank cap may be clogged with the ventilation valve, the motor simply does not pump gasoline. Purge everything and work!
Be sure to look at the connection of the carburetor to the intake manifold! Elsi there sucks air and there is no tightness to eliminate!
The dosing needle hangs up is 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 to check it is necessary to remove the plastic sheathing, break your fingers on the latches, but anyway, sooner or later you will have to climb there.
Everything whole, clean, works?
Trying to adjust. We take a long screwdriver, find the idle speed adjustment bolt (it is located on the throttle), twist it a couple of turns so that the damper opens slightly. We start. Does it work smoothly? Then let’s move on. Won’t start or stall? Opens the damper until it starts up stably.
Then we adjust the quality of the mixture by screw L. It is necessary to achieve maximum idle speed. Here the principle is the opposite, the more the bolt is unscrewed, the richer the mixture. After that, the quality of the mixture is adjusted at maximum speed with the screw H.
If the carburetor adjustment does not work, then it needs to be disassembled. Watch the membrane, clean the jets and internal passages. For this, it is necessary not only to have a repair kit, but also, preferably, a spare carburetor.
First candle
The first step is to unscrew the candle. If it is wet, the ignition system is faulty. Try to wipe the spark plug, put it in the cap, attach it to the engine, jerk with the starter. Is there a spark? If not, then you need to change the candle.
Replacing the spark plug didn’t help? Then you need to watch the magneto, cable, ignition coil. The cable is ringed, the coil is checked for resistance (the multimeter is in the resistance measurement mode at 200 Ohm, one contact to ground, the other to the output of the coil, should show from 0.4 to 2 Ohm).
Sometimes the magnets on the flywheel get dirty, or the key is licked off, and the ignition moment flies away. Chinese shit throws up all kinds of surprises, but for the most part, everything can be revealed visually.
Be sure to pay attention to the plaque of the candle. If it is black, the candle is smoked, then the mixture is rich, or you have mixed the fuel incorrectly. If the plaque is white, it means that the mixture is poor, and the engine could already die of temperature. Ideally, the color should be brick, light, without much plaque.
Again, if the black candle is dead, you should not immediately sin on the carburetor and ignition. Screw in a new one, see what the plaque will be. Maybe the candle was just of poor quality.
What is the resource of the Chinese lawn mowers?
A Chinese or Russian lawn mower is capable of working about 500 hours. But this is with the right mixture, good oil, good factory assembly. If a person pours gasoline from one good gas station, precisely measures the same oil in a beaker, regulates the carburetor for the same mixture, the fuel burns correctly, then the longed-for half a thousand hours of motor life is quite an affordable bar.
But here we must also not forget about the Chinese marriage. They even balance the shafts on the knee, install the cheapest bearings, and stamp carburetors with clogged channels. If a person understands the principle of operation of a two-stroke engine and a carburetor, understands how to sort it out, then he can eventually assemble an almost perfect trimmer.
In general, if we consider a Chinese lawn mower as a space for creativity, then even its breakdown is a reason to learn something new, this is a construction set for a man.
If you need a tool, then you should look for a Japanese analogue, or switch to an electric model.

Checking the fuel mixture
Before starting the engine of the gasoline streamer, check the presence 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). Prepare the oil-fuel mixture strictly according to the instructions. Calculate its amount based on real needs. Excess gasoline left over after work loses its quality over time.
Why the lawn mower won’t start troubleshooting
Caring for the backyard plot, summer residents periodically encounter the fact that the lawn mower does not start. There are many reasons for tool failure. To correctly diagnose the problem, the owner of a useful unit in the country needs to know the device and the principle of operation of its individual parts.

Rules for the operation and storage of lawn mowers
In order for the lawn mower to start well in the future, you need to provide it with good storage and operation conditions:
- During operation, carefully monitor the cooling system, carefully and in time clean the channels in the housing, as well as the ribs of the starter;
- If necessary, use solvents, kerosene and other detergents for cleaning;
- Do not clean the instrument while hot; let it cool;
- Strictly follow the instructions for 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, since over time it decomposes into heavy fractions, which will definitely clog the carburetor channels;
- After draining the fuel, let the trimmer idle until it stalls, this will help completely remove the remaining working mixture.
Before winter storage, follow these steps:
- Disassemble the braid completely, rinse and clean all the details you can;
- Inspect the parts for damage, if necessary, eliminate distortions, tears, bends and any other malfunctions;
- Fill in a sufficient amount of oil into the gearbox and clean the air filter;
- You can partially disassemble the motor, rinse, blow out and grease all moving parts;
- In order to lubricate the piston, you need to unscrew the spark plug, raise the piston to the dead center with the starter, pour a little oil into the spark plug hole and turn the crankshaft a couple of times;
- If you are storing the lawn mower outside the house, wrap the engine with oiled rags.
