John, When I was doing my check ride with the pilot examiner one of his observations was that I was too abrupt with my throttle movements. He wanted me to pull it out slowly and gradually when coming in for a landing and not push it in too fast when increasing power. I can't say that it will solve your problem with backfiring but it is another place to look. O.T. He was 76 and rode a motorcycle. Mike @C35
