i had my stock form 4v cleveland at the track this last weekend and was getting a miss, so i changed the plugs and noticed that the #3 n 4 plugs looked like new and the other six looked fowl. what would cause this? took the carb bolws off and no issues there. fuel pressure was a hair low 5 lbs. fixed that.
