What causes spark plugs to go bad fast?
Overheating Damage: Overheating spark plugs can cause the electrode to wear faster. Oil Contamination: If oil seeps onto the spark plug, it will foul the tip. This creates damage and additional wear (oil seeping into the combustion chamber is something that happens over time as seals begin to fail).
How long does an ATV spark plug last?
Generally speaking you will want to replace the spark plug(s) after each 100 hours of use. This assumes of course that your engine is running normally and you are not experiencing problems like a “rough engine” or an engine that fails to catch while the ignition is turning over.
What are the two most common causes of spark plug failure Why?
Many factors can cause a spark plug to fail; from incorrect heat ranges to improper gapping, to chemical contamination. Yet 90\% of spark plug damage claims are due to improper torque. Proper installation torque is critical in the plug’s ability to dissipate heat out of the combustion chamber and into the cylinder head.
How do I stop my spark plugs fouling?
Quick Fix for Fouled Spark Plugs Auto Parts stores sell spark plug cleaner devices that sand blast the end of the spark plug to remove deposits. If you use one of these devices,make sure no sand remains trapped between the spark plug electrode and shell before they go back in your engine.

When your ATV keeps fouling spark plugs, there is likely an underlying issue that should be addressed before installing new plugs. Fouled spark plugs can cause engine misfiring, reduced engine power, poorer fuel economy, rough idling, increased emissions, and in some cases, not being able to start the engine at all.
How tight should spark plugs be tightened?
Confirm that the thread reach of the spark plug is the right one for your engine. Tighten the spark plug finger-tight until the gasket reaches the cylinder head, then tighten about ½ – ⅔ turn more with a spark plug wrench.
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.
What causes carbon build up on a spark plug?
Carbon fouling happens when the car’s air and fuel mixture is too rich, which means the proportion of fuel is too high. It results in incomplete combustion, leaving behind a carbon buildup on the spark plug’s firing end. Simply put, carbon fouling is a symptom of a fuel problem, not a spark plug problem.
