Wet spark plug on a gas trimmer. Engine flooded.

Surely many people using small motorized equipment know what a “filled” candle on an engine is and what unpleasant situations arise because of this. Very often, using the equipment just acquired, many do not check the condition of the electrodes of the spark plug after updating fuels and lubricants, but remember this only when the first malfunctions occur.

Filled lawn mowing engine.

If there is still at least some appearance of a spark discharge on the electrodes of a wet candle, then a spark discharge on a “filled” candle will no longer be possible. We hear about “filled” candles more often than about “filled” engines. It’s even hard for many to imagine such an engine until they face it personally.

Wet spark plug or filled candle. This is the main symptom of either a non-working spark plug, the absence of a high-voltage voltage on the spark plug electrodes, or re-enrichment of the fuel mixture supplied to the engine working chamber.

In addition, cases with low-quality fuel, low-voltage and low compression ratio can be attributed to this. As a rule, one thing entails some other manifestations and you can easily get confused in determining the main, main cause of the malfunction.

Spark plug. The next lawn mower, or gas trimmer, where we could not start the engine, fell into our hands. No recommendations from observers and “friendly” neighbors even helped. We replaced the spark plugs with new ones, but there was no result, and each successive candle was twisted wet.

Lawn mowing engine air filter.The gas trimmer engine was opened in stages. The air filter ring was completely moistened with fuel. In the compartment where the filter element is installed, there was a large amount of fuel.

The wet filter capacity decreased, and even with a dry spark plug, the engine could not start because the wet filter element blocked the supply of the required amount of air. The spark plug electrodes immediately, at the first attempt to start the engine, flooded with fuel.

Silencer for lawn mowing.Through the mounting holes of the muffler, on one of the mounting studs, an oil stain was clearly visible. Traces of oil may appear when the fastening nuts are loosely tightened, when the waste oil vapor and exhaust gases leak through weak seals, but on this lawn mowing the tightening of the nuts corresponds to the required force.

And in the silencer itself we found about 50. 60 ml of fuel. Not the oil, but the very fuel that was in the fuel tank.

Lawn mowing engine. When opening the engine, we expected to find some kind of surprise, and this was not a vain expectation. A certain amount of dense soot deposits was present on the piston. The piston rings that are lying down and the soot layer on the piston indicated that when operating with a lawn mowing, the temperature regime of the engine, which was working on a re-enriched mixture, was exceeded.

Many manufacturers write directly on the container that the oil has good anti-wear, lubricating, anti-corrosion and temperature properties. But none of them will write: “Do not overheat the engine!” or “Strictly adhere to our recommendations!” It’s hard to say what was poured in place of oil, or poured oil nemerno.

Crankcase engine.What surprised us most was the crankcase, which turned out to be filled to the brim with fuel. It happens when a certain amount of fuel is collected in the engine crankcase, but it is rare for us that the crankcase is completely filled with fuel.

The engine worked ‘in a sweat’, and the operator did not pay attention to fuel consumption, increased smoke, lower engine speeds. Lawn mowers engine flooded on the very edges of the crankcase.

Carburetor lawn mowers.When disassembling the carburetor, there were no difficulties. Outside, the carburetor of the lawn mowers was wet and dirty, which indicated a leakage of fuel, but we did not find the spot of leakage during an external examination.

And inside the carburetor there were dense deposits located along the edge of the hole in the seat of one of the membrane valves, which indicated that this valve worked poorly when its petal did not press tightly against the seat.

One reason for a flooded lawn mowing engine.

After examining the main elements of the engine and interviewing the owner of the lawn mowers, we still identified the reason that led to such consequences.

Inattention of the operator, who, perhaps, accidentally touched the choke control lever and turned it into the “OFF” operating state, in which the air supply turned out to be limited, implying the opening of the choke.

It is possible that the operator did not understand the meaning of the “ON” and “OFF” flap position indicators, and got confused in this.

In short, the human factor is present in all the unpleasant situations that occur during the operation of the equipment.

Lawn mowing does not start: causes and remedies

Diagnosis of the reasons why the lawn mowing does not start. The quick return to life of Chinese and domestic lawn mowers with a two-stroke internal combustion engine.

It happens that a two-stroke motor does not even show a flash in the cylinder, but sometimes it picks up, and then it stalls. Do not be sad, this Chinese consumer goods can be repaired directly on the knee using a minimum of tools.

Before starting the diagnosis, you need to make sure that the engine rotates with a small resistance. If there is no compression in it, then further is useless, and you need to change the piston (this is also nothing complicated, everything is like a designer).

The first is the candle

The first step is to unscrew the candle. If it is wet, then the ignition system is faulty. Try to wipe the candle, put it in the cap, attach it to the engine, pull the starter. Is there a spark? If not, then you need to change the candle.

Replacing the candles did not help? Then you need to watch magneto, cable, ignition coil. The cable rings, the coil is checked for resistance (a multimeter is in the resistance measurement mode at 200 Ohms, one contact per mass, the other to the output of the coil, it should show from 0.4 to 2 Ohms).Sometimes magnets are dirty on the flywheel, or the key licks, and the ignition moment flies away. Chinese shit throws up various 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, it means the mixture is rich, or you incorrectly mixed fuel. If the coating is white, then the mixture is poor, and the engine could already die from temperature. Ideally, the color should be brick, light, without much plaque.

Again, if the black candle is dead, do not immediately sin on the carburetor and ignition. Screw a new one, see what the plaque will be. Maybe the candle was of poor quality.

The second is a carburetor

It is not necessary to disassemble the assembly immediately, especially if the engine stalls after starting or does not hold idle. First, try to change the fuel, there may be an excess of oil in it. You can inject a cleaner into the air filter, give the motor a little “crawl” at maximum speed.

Next, we go in order. An air filter, a fuel filter (it can be outside and in the tank), a fuel pump button, and hose integrity. Gas tank plug. The ventilation valve may be clogged, the motor just does not pump gasoline. Blow it all. And it will work!

Be sure to look at the connection of the carburetor with the intake manifold! Elsi sucks air there and there is no tightness. Eliminate!

The dosing needle hangs. Also a problem in some models. It is enough to push it down, or remove and sand it with velvet.

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

Does the whole, clean, work?

We are trying to adjust. We take a long screwdriver, find the idle speed adjustment bolt (it is located on the throttle body), twist it a couple of turns so that the shutter opens slightly. We start. Does it work smoothly? Then move on. Doesn’t start or stall? Slightly opens the shutter until it starts stably.

Next, adjust the quality of the mixture with the L screw. 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 screw H.

If the carburetor adjustment has not given its fruit, then it must 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.

What is the resource of Chinese lawn mowers?

Chinese or Russian lawn mowers can work out about 500 hours. But this is with the right mixture, good oil, good factory assembly. If a person pours gasoline from one good refueling, accurately measures the same oil according to the beaker, the carburetor adjusts the same mixture, the fuel burns correctly, then the desired five hundred hours of engine life is a perfectly affordable bar.

But here we must not forget about Chinese marriage. They even balance the shafts on the knee, put the cheapest bearings, carburetors are stamped already with clogged channels. If a person understands the principle of the two-stroke engine and carburetor, understands how to sort it out, then he can eventually assemble an almost perfect trimmer.

In general, if we consider the Chinese lawn mowing ground as a space for creativity, then even its breakdown is an occasion to learn something new, this is a designer for a man.

If you need a tool, then you should find a Japanese analog, or switch to an electric model.

Pours A Candle On A Lawn Mow What To Do

The owner of the suburban area can not do without a lawn mowing or trimmer. However, during its operation, of course, situations arise when this unit for some reason ceases to start. And the circumstances of this you like a lot. Let’s find out why a gas trimmer does not start.

Does Not Start Lawn Mow Spark Eat Candle Wet

To find out why the gas trimmer does not start well or stalls permanently, you need to check the operation of all the main components of the unit one at a time. It is especially important to do this after a long storage of lawn mowers. What you need, the main prerequisites for this behavior of the trimmer are as follows:

Use for cleaning the carburetor and special flushing.

  • If the carburetor gaskets are worn, you need to change them. And if the density of this device is violated, you will have to find the faulty part of the carburetor and replace it.
  • The trimmer may not start due to wear on the piston group. But it is better to change such details of lawn mowers in a car service.
  • Trimmer fishing line. Which one to choose?

    Immediately after buying a grass trimmer, we are faced with a lot of questions. How to use it correctly, how to refuel (if we are talking about a gasoline tool) and it’s clear which line is better to choose. You find the answer to the last question in the text of the article.

    A beautifully maintained lawn is the decoration of any area. And to keep his attractiveness helps a constant haircut. In this case, it will not do without a lawn mower or trimmer. The text of the article will talk about the intricacies of choosing a gas trimmer.

    In most cases, this happens with beginners, when they pass the “cotton” on the closed air damper at the first start-up and continue to pull the starter handle, so there is enough gas in the combustion chamber, and not enough air prevents the gas from catching fire.

    A candle pours on a lawn mow

    1. With a candle key, unscrew the candle and check its condition. If the candle is wet and the spark of course, then it was flooded. We open the air damper, turn on the switch button, squeeze the gas “all the way” and start it. Excess gas should come out of the exhaust saw and the saw will start.
    2. With a candle key, unscrew the candle and check its condition. If the candle is wet and there is a spark, then it was flooded. Turn the chainsaw with the hole of the candle down and turn the starter 10 times, with all this excess fuel will flow out of the engine cylinder. Then wipe the candle dry (bake), or change to a new one and try to start the engine exactly following the operating instructions. If the candle is completely dry, then this means that the engine does not receive fuel. And because it is in the tank, then there may be a problem in the carburetor. You can draw a little consistency into the syringe, inject it into the cylinder, twist the candle and try to start the engine. If the engine started up on this issue stalled, as it should, the problem remained and you need to contact the service center.

    Probably garden tools are useful and effective, but there are times when the technique is refused to work. They included a trimmer, which has the option of mowing a small meadow and large lawns.

    There are various reasons why a gas trimmer does not start:

      The most common reason for breakage lies in the wrong choice of fuel. Often, very economical users of the device pour something incomprehensible into the tank, but not fuel at all with the usual octane rating. Bad fuel, which was kept in a plastic canister for a long time, has a terrifying effect. A device that has lost operability therefore sets sail for a complete bulkhead of the mechanism.

    Why the lawn mowing does not start. We troubleshoot

    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.

    Dry the canal for at least 30-40 minutes. Otherwise, there is a risk of re-pouring a new candle.

    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. Exit. Replacement of a failed gasket;
    • 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.

    Remember, careful observance of the rules will allow you to forget that it is bad to start a lawn mow for several seasons.
