Why the plug in a brushcutter floods

Why the grass trimmer fills up the spark plug?

Wet spark plug or flooded plug. this is a major sign of either a non-functioning plug, the lack of high-voltage on the electrodes of the plug, or the over-enrichment of the fuel mixture, fed into the working chamber of the engine air filter engine lawnmower. The gasoline trimmer engine was opened in stages.

Why does the spark plug on the chainsaw fill up: causes Poor gasoline quality. Incorrect algorithm for starting the chainsaw, which is often “sinned” by inexperienced owners. The air filter is clogged and can no longer do its job. Ignition system malfunction.

What to do if the lawnmower won’t start?

To rule out this cause, clean the valve and try to start the lawn mower with the tank cap not completely turned in. 2. If the lawnmower does not start, remove and clean the fuel filter and check all carburetor parts before trying to start it.

Measure the gap between the electrodes with a wire gauge; the gap should be 0.7 to 0.8 mm. If adjustment of the gap is necessary, do so by carefully bending the side electrode.

Getting the machine ready to start

It is important to study the manufacturer’s manual if only to find out whether the engine has a four-stroke cycle (like Forte, Centaur, Lifan, Zubr) or a two-stroke cycle. This is important to know, since models with a two-stroke motor (like the Mole cultivator) need a special combustible mixture consisting of a certain proportion of gasoline and oil. Because of the mismatch of fuel equipment will stall, and can also damage the spark plugs and fuel line, which is fraught with failure of the gasoline pump. and it is already a direct path to an expensive repair in the service station. You can tell if the fuel is suitable for your motorcycle by the smoke. If the quality of the gasoline is bad, it will have a white color, as is the case with a strong tilt of the car.

The fuel quality is also important for a diesel engine tractor as well. it does not start in winter, or it starts but soon stops, if its engine is filled with summer fuel, because at low temperatures it starts to get thick and clog the fuel line.

Starting the motorcycle, both in summer and winter, should be carried out in a certain sequence. For example, to start the Krot motocultivator, the following procedure is carried out:

• open the petrol valve;
• put the choke lever in the “Choke” position;
• Turn off the ignition and crank the motor a few times with the manual starter;
• restart the engine and move the lever to the “Run” position.

It is not rare that such situations happen when the power aggregate is easy to start but stops after a few seconds. In that case it is necessary to check the sump patency, maybe the reason is that the tap is clogged. then it is cleaned with gasoline.

To start the engine with diesel engine (such as Zubr, Kaskad, Centaur, Neva) will be a bit more difficult than with the Mole. Start-up of a diesel engine begins with the “bleeding out” of the fuel line, that is with the release of air accumulation in it. For this purpose:

• open fuel tap;
• untwist the connections of the fuel-extraction duct until the fuel appears;
• tighten connections and blow out nozzles.

Start-up of a power tiller after the winter or a long idle time also has its own nuances. In order to get the machine in working order do the following manipulations:

Well, of course, before you start the motor, whether it be a Centaur, Cascade, Neva or Zubr, check all the connections, including nodes transmission, clutch, starting mechanisms, and if necessary, carry out their adjustment.

Carburetor breakdowns and how to repair it

Often a power tiller does not start because of clogging inside the jets or carburetor filter. A sign of this will be a completely dry and clean spark plug of the machine. Repair is carried out in the following order:

• First remove the carburetor unit;
• Disconnect the fuel fitting and blow it out with compressed air from a cylinder;
• After that, purge the combustion chamber and fuel pipes;
• Reinstall the carburetor and try to start the cultivator.

If after that the cultivator does not start, then check the position of the float placed in the combustion chamber of the machine. Setting the part is done with the help of special screws. by turning them clockwise, you raise the float, and by turning the screws against the clock hand, the part is lowered.

Trouble in the ignition system

Such elements as magneto, spark plug, preset cap and high-voltage wire most often succumb to oxidation, as a result of which they inevitably malfunction. If there is dirt and moisture on the high-voltage wire, they are the reason of its breakdown.

Weak spark or its complete absence most often indicate a lack of efficiency in the work of the spark plug, due to which the motocultivator refuses to start. In such a case, check the condition of the gaps and the distance between them. It is best to do it with a special dipstick. the normal value for work should be 0.8 mm. If there is a need, it is necessary to completely remove the formed soot from the outer surface of the insulator and the metal parts available in the spark plug.

Engine readiness before start-up is affected by the serviceability of the piston group elements. As they constantly work in harsh operating conditions, their surfaces succumb to intense heating, which leads to breakage of ICE cylinder, pistons and rings. If the machine won’t start, you will need to check its exhaust and intake valves. It is often the case that they do not adhere properly to the saddles. In such a case it is necessary to correct the fault as quickly as possible and then try to start the machine again.

Another part that often lends itself to breakdowns is the regular muffler of the cultivator. On the walls of the element inevitably accumulate combustion products and residues of exhaust gases, leading to an inability to start the cultivator. With a large amount of these substances, sooner or later the engine will stop starting. To eliminate this malfunction, you will need to remove the muffler completely and clean it with compressed air from a cylinder.

All of the listed faults and troubleshooting methods will work if the motor cultivators manufactured by Sungarden, Texas and Neva brands do not start. These manufacturers’ models are straightforward. therefore, even a novice can easily repair them.

The power tool does not start in the cold. The grass trimmer Champion does not start

As well as any technique, are subject to various breakdowns. Often at the beginning of the dacha season the owners of such a tool complain that the grass trimmer does not start, and we have to look for a long time for the cause of malfunction.

For those who have recently purchased a grass trimmer and are still on “you” with this technique, the information about why the grass trimmer does not start and what to do in such a case will be useful. So, let’s find out what can cause it.

Does not start the gasoline trimmer for grass. 10 possible causes

Before you try to fix the tool yourself, carefully study the manual of the tool. Perhaps the information contained in it will lead you to this or that idea. Otherwise, you will have to look for the cause of the malfunction by the method of selection. It may be one of the following:

• The toggle switch on the boom is not in the “on” position.”. This is one of the elementary steps, but sometimes beginners forget to turn on the tool before starting it.
• Such errors also include the lack of fuel in the tank. If you run out of fuel and you forget about it, just fill the tank (usually located near the engine) with gasoline AI-92.
• Lack of, improper mixture, or improper proportion of engine oil. Ideally, you should regularly add no more than 50 grams of oil. This serves as extra lubrication and keeps your grass trimmer’s engine running. Also consider that oil comes in different types (“synthetic”, “semi-synthetic”, “mineral”). they all affect the mechanism in different ways.
• If the grass trimmer does not start after the winter, drain the remaining fuel in the gas tank and replace it with fresh fuel. This is especially true for small low-power trimmers with small motors, sensitive to poor mixture. In addition, over the winter at the bottom of the gas tank can be formed sediment, which causes problems with the work of the device.
• Excessive pumping of fuel can also be one of the reasons that the trimmer for grass stalled and does not start. When the choke is blocked, the spark plug is flooded with fuel. It should be unscrewed and dried and then inserted in its place and try to start the engine by holding the throttle trigger. It is desirable to check before that for the presence of spark between the electrodes. If you don’t get a spark, you need to replace the spark plug.
• Problems with the filter. If your trimmer for grass poorly starts, remove the air filter and run the tool without it. If it works. the filter should be replaced with a new one. As an option. thoroughly clean and blow out the old one, but the replacement will still have to be done sooner or later.
• Grass trimmer stalls and won’t start? Try to clean the so-called breather. an element designed to equalize the pressure in the gas tank. Cleaning can be done with a normal long needle. A clogged breather plug is often the cause.
• The machine has removed blades. some models will not work under this condition.
• Leaky seals. You can check it with a pressure gauge. If the pressure begins to drop, you should determine which part of the carburetor is defective. Most often the carburetor gasket is worn.
• Sometimes after a long period of work, you may notice that the grass trimmer has overheated and will not start. First, it is important to know that it is imperative to take breaks. The amount of continuous operation time recommended for this model should be specified in the manual. Also, the problem of overheating may be a faulty ignition coil or air cooling system that prevents overheating.

If none of these actions have produced results, you should contact a repair shop or service center.

The use of gasoline mowers is common and relevant today, as having good power and productivity, these tools help people to cope with the surrounding vegetation: grass, weeds, sprawling lawn and so on. But there are situations when the lawnmower does not start under all circumstances. There can be many reasons for this, as well as external manifestations. For example, a working lawnmower may not start after winter downtime, under the influence of adverse seasonal conditions or in the case of internal failures. It happens that the engine fills the spark plug with fuel.

As a construction of the drive and other systems, which included: gasoline motor, gearbox, ignition elements, etc., gasoline tool is constantly exposed to the action of mechanical stress. In most cases, these are the reasons when the gasoline trimmer refuses to work. With technical expertise and the necessary knowledge, the store “KosiKosa” offers not only the opportunity at a low price, but to take it to the service to identify the cause of the lack of starting and troubleshooting.

What to do if the gasoline grass trimmer does not start

So, if there is a situation in which the lawnmower does not start before the next cleaning operation, the reasons are first found out to understand why it refuses to start and how to make the scythe come back to life. In this case it is necessary to:

• To inspect the external condition, it may be the cause in the starter;
• Check if there is a spark on the plugs, and the start does not work, probably not enough fuel in the carburetor. You should apply gas slowly when starting, so that the carburetor fills with gasoline when ignition is hot;
• If the grass trimmer does not start when cold, you need to check the spark plugs or check the ignition.

In any case, a breakdown, for which the gasoline grass trimmer refuses to start, exists, and to solve this problem you may need a partial repair of gasoline equipment or a full. By contacting “KosiKosa” you can get information about which of the causes you have. Also, for repair work, we have available ignition systems, the necessary spare parts, as well as other products that will be useful to the owner of the grass scooter.

Why does the plug on the scooter fill up [New research]

Experienced owners of the vehicle know that in the cold season, for some reason sometimes the scooter does not start. Some people get into such an unpleasant situation in the summer, but much less often. The problem can have many causes, but the most common is a flooded spark plug.

This can happen regardless of which fuel system, injector or carburetor, is installed on your scooter. The construction of the spark plug and the ways to fix the problem do not change significantly.

In the case of the injector, the fuel supply is regulated by the electronic control unit. There is more oxygen in the cold air. Understanding this, the ECU increases the flow of gasoline. If the spark in the spark plug is not strong enough, unburned fuel will remain on the spark plug electrodes. Then the iron horse can no longer be started.

Causes of the problem

Even if the engine can be started, the problem will occur again. If it is not the first time the spark plug on the scooter pours, it is worth finding and fixing the problem. The culprit may be:

• Contaminated air filter. If there is not enough oxygen in the fuel mixture, the gasoline will not be combusted completely and will remain on the spark plug.
• Mixture quality screw. If the carburetor is not properly adjusted and the screw is tightened too much, a similar problem will occur.
• Low-quality fuel. Gasoline diluted with another fluid may also be the cause.
• The ignition system itself is defective. No spark occurs, or it is not powerful enough to ignite the mixture.

Sometimes, if the spark plug is wet, it is enough to simply dry it out. But this will not eliminate the problem or prevent the occurrence of this unpleasant situation in the future. While almost any of the problems described can be solved by yourself.

Start the engine

Yesterday the scooter or moped was working normally, and in the morning its engine simply will not start. It’s probably caused by a primed spark plug. You can, following the instructions, take out and dry the candles, but if there is not enough time, it is worth trying a folk method.

To use it, first you need to let the scooter stand for a little time. 5 minutes. Then you should fully unscrew the gas handle and twist the starter. Continue for about fifteen seconds. At this time there will be no fuel in the chamber, so it will be blown with air. Most likely, such a simple operation is enough, and the engine will start. This should work on both a 2hp and 4hp scooter.

If the iron horse does not start, you have to use another way. It will take some time, patience and a spark plug wrench. First, you should unscrew the spark plug and make sure it’s the problem. It can be cleaned with a brush and then dried with a hair dryer. However, any heat source will do: burner, oven or gas burner. Next, it is recommended to blow out the cylinder the same way as with the traditional method. Then put the spark plug back in. Now the engine just has to start. If this hasn’t happened and now, you’ll have to replace the plugs and run diagnostics.

Once the engine has started successfully, it is tempting to leave it as it is. However, it is advisable to find out what the problem is. Regardless of whether a spark plug on your moped or scooter fills up, it is likely that some parts need to be cleaned or replaced. But even if the reason is only that the vehicle is not new, there are ways to avoid plugging in the future.

Troubleshooting

First of all it is necessary to understand what the problem is. Even if the cause has been found, it is worth paying attention to other possible problems, since they may be connected with each other. Required:

• Check the battery. Keep it charged during the cold season, because it indirectly determines the power of the spark. It is especially important for older vehicles, because their battery life is already partially used up.
• Verify the quality of the fuel used. You ought to buy gasoline only at reliable gas stations. With a poor power supply, the iron horse can let you down at the most inopportune moment. No matter if the trip is planned on the moped alpha or scooter symphony.
• Choose the right oil. Its quality and viscosity also matter. Use winter oil in cold weather.

It’s easier to prevent trouble than to repair it later. For this purpose it is necessary to untwist the engine and drive at high revolutions about once a month. That way the fouling of the crankcase can be cleaned. A charged battery, high-quality fuel and regular care will help to avoid unpleasant situations. Honda Dio or Suzuki, your scooter will serve you faithfully.

The gasoline trimmer likes cleanliness. The air filter and fuel must be checked for cleanliness. Gasoline, bought at the gas station, is better to stand for 2 days and pass it through a simple filter. a piece of baize cloth.

Check the electrical equipment as follows:

Unscrew the plug, inspect the gap between the electrodes. We set the correct gap between the electrodes, it is possible to do it “the old man’s way”. Take a razor blade, break it in half and put a home-made probe between the electrodes. If the blades fit snugly, the clearance is perfect.

Put the cap of the high-voltage wire on the spark plug and lean the plug against the metal surface of the engine. We yank the starter a few times. If the spark is well struck to one point, the gap is set correctly. If not. the spark is weak or “wandering”, you need to re-adjust the gap between the electrodes.

Causes of malfunction

Filled spark plugs can prevent the scooter from starting or make it unstable. So, what could be the cause:

• A clogged air filter. Not enough air supplied to the scooter carburetor enriches the fuel mixture. So, a large volume of fuel has no time to burn in the combustion chamber and the spark plug gets dirty.
• Improper carburetor adjustment. A twisted mixture quality screw on a carburetor has almost the same effect as a clogged air filter.
• Faulty ignition system. There are several scooter faults at this point: faulty plugs. bad wire. ignition coil problems. wrong advance angle (for example, the vehicle is already old).
• Poor quality fuel. Gasoline diluted with another fluid greatly affects the contamination of the spark plug.

Oddly enough, on an injector, it can also flood the spark plug somewhere. This usually happens in the winter on worn engines. Since the quality of the mixture is regulated by the electronic control unit (ECU), it would seem that the plugs should not fill up.

However, poor compression, discharged battery, bad starter, insufficiently powerful spark and improper electrode gap do not allow the scooter to start at subzero temperatures. The ECU supplies more fuel to the cylinder in freezing temperatures because there is more oxygen in the cold air than in the hot air.

For a number of reasons described above, the vehicle does not start and floods the plug.

How to avoid the filling of spark plugs with gasoline?

The main criterion is to keep the battery charged and the starter operable. To do this, you need to create the right conditions so that the scooter can start even on a cold morning. In addition, it is necessary to fill only high quality oil, and gasoline must be with the required octane number. this parameter is specified in the instruction manual of the scooter. As a preventive measure is suitable cleaning and adjustment of the injector nozzle.

There is also a folk remedy that will help avoid that the candle will be flooded. To prevent this outcome, you should periodically accelerate the scooter to the maximum in winter and drive at a slightly higher than average speed. This increases the load on the engine, which results in self-cleaning of the carbon and fuel in the combustion chamber.

By following these simple requirements, you can not only avoid the problem of flooded spark plugs with gasoline, but also increase the life of the engine. This can be controlled on their own without having to call for help from a service station.

One of the problems of scooter owners is the flooding of spark plugs with fuel. Before you solve this problem, you need to find the cause. It is possible to do it yourself without costly repairs by specialists.
