If so, stick it on the engine. Get your idle up to 900 rpm as suggested. Diddle with your timing until you have the highest vacuum signal. It needs to be as steady as possible despite the rough idling cam.
Once that is set, turn your idle mixture screws in until the rpm begine to drop. Then turn them out until you have the highest steady vacuum signal.
If you still have issues other than a lumpy cam idle let us know.
We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind. - Stu Harmon
