I've had good luck with removing the plugs and spraying them off with brake cleaner, blowing out the black junk (removed by the brake cleaner), and then reinstalling them. I usually only have to "clean" the leading plugs to be successful. It normally starts right up after that. I guess the trick here is to use brake cleaner so that you remove the black deposits. (No, I don't have a favorite brand.) This probably goes without mentioning, but be careful to keep the ignition off while purging the excess fuel when cranking without plugs. One spark and you might get to start the building process all over from the beginning. =20 Mark S.=20 I removed the plugs, wiped them off and dried them, and cranked the engine to blow out all excess fuel. The plugs were practically new with only a few hours of ground running on them. They are very clean looking, but with some black around the ceramic portion deep within the plug. Each plug fired when tested outside of the engine. These are stock NGK plugs as specified for the engine.
