The most common cause of black smoke is a clogged air filter. Replace your mower`s air filter and this should resolve the problem. If you`re still seeing smoke, the air-to-fuel ratio may be off, in which case the lawn mower`s carburettor might need to be adjusted (ideally by a lawn mower repair specialist).
The engine is burning off the excess oil, which is causing the smoke. This can be fixed easily by making sure the oil is at the correct level. White fuel can also occur if any fuel gets into the engine itself so this can happen if you are mowing on a gradient. It is often completely harmless and is easily fixed.
Lawn mowers can overheat due to a number of different reasons, from the weather down to the state of the grass and even because of the way you use them. Here are a few common causes of mowers overheating.
Your lawn mower`s carburetor regulates the ratio of gasoline to air mixture. If the carburetor isn`t getting enough air, the mixture has a higher percentage of gasoline, which can create black exhaust smoke. It`s possible that a dirty or clogged air filter is preventing sufficient airflow into the carburetor.
If the smoke is black or if you continue to see blue or white smoke after the mower has run for 10 or 15 minutes, there may be an engine problem behind the smoke. In such cases, your first step should be to check the air filter, after the mower cools down.
In extreme cases, you will need to replace your head gasket. At the first sign of white smoke you can try head gasket repair treatment to seal the leak before you do serious damage to your engine.
To fix blue or gray smoke: The easy way is to add a bottle of Motor Honey Oil Treatment to your motor oil with each oil change. It`s specially designed to reduce oil burning and stop smoky exhausts. The hard way is an engine overhaul, which is about a hundred times more expensive and a thousand times more work.
A faulty or dirty spark plug could be the reason your lawn mower won`t stay running. It might produce the initial spark, but the spark won`t be enough to keep the engine running if the plug is clogged with dirt and oil. Spark plugs are usually located on the front of a push lawn mower and connected to a black cable.
If at any point you detect the smell of burning rubber while the engine is in operation, discontinue use immediately. The belts that power the dethatcher mechanism are made of rubber, and this smell indicates that there is stress on the belts causing them to melt while the engine is running.
You will be able to tell if the motor has burnt out as it will emit an electrical burning smell, which will usually happen if your mower has been put under excessive strain.
Yes, the flashes of light are from the electric brake or brush arcing. This is normal and has been present on all of our previous mowers, but the previous mowers had a black housing instead of orange and this made it harder to see the flashes of light.
When cleaning an electric mower do not use a hose or a pressure washer. Water can get inside the motors and cause corrosion. Use a lubricant like WD-40 on the wheels. Most wheels are made of plastic, but the axle is metal and the bracket inside the wheel is also metal.
Although battery-powered mowers require little service (no gas, oil or spark plug changes), you should take them to a specialist once or twice a year to have the blades sharpened.
Consumers who use electric lawn mowers should be careful to not overcharge their lawn mower batteries to prevent them from catching on fire.
A burning rubber smell
If your car smells like burning rubber, turn off the engine and check under the hood to see if anything looks out of place. Chances are that the smell results from a belt or other part slipping and rubbing against the hot engine. If you can`t identify the problem, take your car to a mechanic.
Lawnmowers can also catch fire while in use, although this is a much rarer occurrence than fires started by lawnmowers being too close to flammable materials.
It usually means that coolant is being burned in the engine, which means that something is drastically wrong. The most common cause of this is a blown head gasket, which can quickly lead to an overheating engine.
To be extra clear, before someone starts arguing with us, white smoke will make your food taste smoky, but in a bad way. This is because this white smoke is a sign that your charcoals aren`t ready to cook with. While this white smoke is billowing, you`ll likely be at low temperatures and getting ash all over your food.
The white smoke is the engine burning off all the excess oil. The fix – drain the excessive oil, and idle the engine until the smoke clears. This may take 5 minutes or so. Too much oil will cause other problems, smoke, poor running, no running, leaks, engine damage.
Black exhaust smoke
“When your exhaust pipe gives off black smoke, one of the things to get worried about are bad or worn out spark plugs. It means fuel burning in the combustion chamber is not being done 100 percent or burnt fully. It also means that air is not being well mixed with fuel to burn effectively.
The most common answer to, “Why is my car smoking but not overheating?” is that there`s a type of fluid that`s landed on the engine. This can be motor oil, fuel, transmission fluid, coolant, or even condensation. It can cause your engine to smoke because it`s burning off that fluid from the engine.
Condensation inside the gas tank is one culprit, but moisture can also enter the system through a loose or ill fitting gas cap. The best solution is to drain the mower`s gas tank and refill it with fresh gasoline. A clogged fuel filter can also cause a mower engine to die.
The spark plugs are worn or damaged
If you find that your lawnmower keeps dying, or keeps stalling while cutting grass, then inspect the spark plugs. Look for signs of damage or wear. Something as simple as a cracked porcelain insulator can mean an electrode has been damaged or burned away.
If your lawn mower starts, runs briefly, then dies these are the four most common reasons that`s happening: Dirty carburetor / clogged carburetor bowl. Old gasoline that has gone bad. Dirty or defective spark plugs.
