Re: HELP PLEASE! Engine Trouble
It's not always that excessive fuel will ruin a spark plug but it may cause misfiring. My guess is the fouling causes the spark to jump the gap to ground. In most cases where the spark plug is new and clean it can be dried out an reused, however, the cause of the fouling has to be eliminated first.
If the spark plug already has oil or carbon buildup on top of the fuel soaking, it's best to replace them. From http://www.briskusa.com/basic_theory...plug_operation Fouling Will occur when spark plug tip temperature is insufficient to burn off carbon, fuel, oil or other deposits Will cause spark to leach to metal shell...no spark across plug gap will cause a misfire Wet-fouled spark plugs must be changed...spark plugs will not fire.
