Why does my snowmobile keep fouling plugs?
Why does my snowmobile keep fouling plugs?
Normally the things that will cause fouled plugs are low compression,bad fuel,too much fuel and sometimes weak spark but with todays ignitions that is rare.
How do I stop my spark plugs 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 do my plugs keep fouling?
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.
Why does my 2 stroke keep fouling plugs?
The most common reasons why your dirt bike has a fouled spark plug are because a dirty air filter, improper pre-mix ratio, carb jetting is too rich, the engine has low compression, or a weak spark.
Why do spark plugs foul quickly?
If the PCV valve is stuck open, the excess vapors and oil droplets can quickly foul the spark plugs. A failed turbocharger can be another source of spark plug oil fouling. The main culprit in these problems is vacuum generated in the cylinders that sucks engine oil past the rings and into the combustion chamber.
What causes black carbon on spark plugs?
Carbon fouled Black, dry soot on the electrodes and insulator tip indicates a carbon-fouled plug. This can be caused by a dirty air filter, excessive driving at low speeds, too rich of a fuel/air mixture or idling your vehicle for too long.
Will a hotter spark plug stop fouling?
Rich air/fuel ratios require a hotter plug to prevent fouling. Mixtures that cause the plugs to read lean may contribute to pre-ignition or detonation. The higher the compression ratio, the colder the spark plug needs to be.
What does black soot on spark plugs mean?
carbon-fouled plug
Black, dry soot on the electrodes and insulator tip indicates a carbon-fouled plug. This can be caused by a dirty air filter, excessive driving at low speeds, too rich of a fuel/air mixture or idling your vehicle for too long.
Is a fouled spark plug ruined?
A spark plug can be cleaned and reused, but it more than likely won’t run at or near the same efficiency as before it was fouled. Given that NGK copper plugs are only a few dollars, it really doesn’t hurt to replace a fouled plug.
