Why does my dirt bike spark plug keep fouling out?
Worn or damaged pistons leak oil which fouls the spark plugs. A too rich air/fuel mixture is a great way to ruin a spark plug. If your bike releases a lot of black smoke you might have a “rich fuel” environment. Bad jetting, bad gas and an incorrect gas to premix ratio all result in fouled spark plugs.
Can anti seize foul a spark plug?
Metal shell stretch changes the heat rating of the spark plug and can result in serious engine damage caused by pre-ignition. Do not use anti-seize or lubricant on NGK spark plugs. It is completely unnecessary and can be detrimental.
Can a spark plug get soaked in gasoline?
by Pete Campbell. A spark plug is an electrical device that provides, as the name suggests, the sparks needed to ignite the gasoline in an engine, which in turn powers the vehicle. However, while the spark plugs typically are designed to be kept dry so they can continue consistently producing sparks, they can get soaked with gasoline.
Can a hotter spark plug help with fouling?
If you can’t avoid a lot of idling or short trip driving, refer to the spark plug supplier’s catalog for a spark plug that is one heat range HOTTER than the standard spark plugs specified for your engine. Increasing the heat range slightly can improve fouling resistance by helping the plugs run hotter.
Why does my car run with no spark plug?
As a result, the next time the spark plug enters a carburetor to ignite the gas, no spark is made, so there is nothing there to ignite the gas. The gasoline-and-air mixture will simply remain that, and the lack of ignition will deprive the car of any power to drive it.
What causes spark plugs to get wet and foul out?
According to AA1Car.com, this occurs when the spark plug fails to fire, or fouls out. This can be caused by a number of variables, such as engine flooding, or excessive moisture build up. Failed vehicle starting attempts eventually lead to wet spark plugs, according to E3 Spark Plugs.
What causes carbon to foul the spark plugs?
If a fuel injector is clogged or sticking open, extra fuel can cause carbon problems. If the mass air flow sensor or oxygen sensors are not accurately reporting the air coming into the engine or the oxygen content in the exhaust stream, it could cause a rich-running condition that can cause carbon to foul the spark plugs.

What to do if your spark plug keeps fouling?
Remove the spark plug and wiring away from the opening. Crank the engine to clear liquid from the cylinder. Reinstall the spark plug and then loosen the lug nut at the bottom of the carburetor until you can see clear gas flow through it then retighten the nut. This should remove the oil from the carburetor.
