backfire/popping exhaust on deceleration answer?
Picking up an old thread here seeking resolution to my issue of popping / back firing in exhaust on deceleration, however I don't have Petronix, but equipped with original points, condenser. Twin Cam. I've given it a complete tune-up, carb rebuild, timing check, etc., but it still pops through exhaust while decelerating in gear on the upper rev end. Did this before tune up as well. Can't imagine all of us having burnt valves?
what was the resolution to this seemingly "common" problem????
