[:'(][:'(] Guys I knew they were bad and i use ngk cm6's for all mine. Well today I did not have a spare cm6 one and I wanted to run a 30 that I just got for a Mustang. Well the engine would not hold an idle and the top end was erratic! I started chasing nettles and after 15 LONG frustrating minutes I decided to remove one from my Waco and SUCCESS!!! The Idle cleared right up and the top end after readjusting was great!! Lessened learned, always have a spare plug!!!
Will be ordering a couple from jody and some props within the week!!! Knew they were bad but never realized they could cause that much trouble!!!
