this isn't for a car engine of mine ( Yet... I'm going to run 1 step colder plugs in the Falcon than the stock plugs, so I know I'm gonna foul them from time to time ). my dirtbike, loves to foul sparkplugs, some of it's my fault. I run the oil mixture a little high in the gas, so I'v fouled the plug a few times, oil fouled it, and even after cleaning it, I can never get it to spark again, always just put a fresh 1 in. if it's just gas fouled, or just lightly oil fouled, to the point it will still run, I put it under the flame on the stove, and it fixes the problem. what can I do to clean the plug off? at school we sandblast, but at my house, my blast cabinent is filled with 20/40 Black Diamond, a little course for a spark plug I think. at school we have some extremely fine blasting sand. I'v seen those air compressor powered " Spark Plug Cleaners " but do they work? I run NGK BR8- ES in it.
