Bobby 0 Posted October 24, 2006 i'll need to get it double checked as my sparkies were black when i changed them yesterday, think its slighty over fueling, when i accelerate quick and put the clutch down the revs come down slowly is that a sign over overfueling? Can normally hear a hissing noise when i turn the engine off, checked for vaccum leaks but couldn't find any might be the drilled airbox releasing the pressure?
