Why do my spark plug keep filing out?
Causes of carbon fouling include rich fuel mixture, clogged air filter, prolonged low-speed driving or idling, faulty ignition system, retarded ignition timing and spark plug heat rating is too cold.
What happens when a spark plug goes bad?
Normal functioning spark plugs will create sufficient spark to ignite the fuel-air mixture fully leaving no residues and lesser emissions. Malfunctioning spark plugs can result in increased fuel consumption and emissions because of incomplete combustion. The lack of proper acceleration is another sign of faulty spark plugs in a car.
How long does it take to replace a spark plug?
Depending on your experience level, it may take you anywhere from 20 minutes to a couple hours to do the job. Before you attempt DIY spark plug replacement, validate that the spark plugs need to be replaced before you spend money on new spark plugs that you do not need, and throw away spark plugs that you could have gotten more use out of.
What to do if your spark plug is fouling?
If one cylinder has oil fouling, a relative compression check can help to assess mechanical issues with that cylinder. Malfunctioning PCV systems are becoming a leading cause of oil fouling in modern engines. These systems have become more than just a spring-loaded check valve.
What to do if you don’t get a spark in your engine?
If you don’t get spark, try a new spark plug before you do anything else, even if the plug looks “good” try a new one. If you have spark and the plug was dry, move on to “Fuel” If you have spark and the plug was wet, replace the spark plug and try starting the engine again with the choke off.

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.
When do spark plugs need to be replaced?
The spark plug should be replaced. Worn and eroded electrodes are symptoms of a spark plug that is past its prime. The plug has been in the engine too long and needs to be replaced. If the electrodes are broken off or flattened, it is likely that the wrong spark plugs are installed.
How can you tell if a spark plug is too hot?
A normal spark plug will appear dry with a grayish color. A wet spark plug can indicate water in the fuel while a white residue on the plug can point to a plug that is too hot. If the plug is black with soot, it can mean that the fuel has too much oil while an eroded plug can indicate a too-hot plug. When to change your spark plugs
