My 1968 Shooting Star used to backfire a lot on deceleration and I was going to check the timing/points etc but didn't get to it, and than one day I re gapped the plug cuz it was way out of spec & the backfiring almost stopped. So being lazy I never got around to rechecking the points/timing etc. I took it out for a long ride a few days ago & noticed it's pinging a lot under load & backfiring just a little on deceleration. Valve adjustment is good so does this sound like I have the timing a little to advanced ?
