John: If the exhaust stack was just replaced I'd expect a leak at the flange(s) or the muffler connection.

Since that time, the engine seems to be backfiring when I close the throttle to land. I checked it today and the backfiring seems to start between 70 and 65 mph. The A&P has checked everything he can think of and has no idea what is causing the problem. I was flying with the canopy closed and wearing a headset today and even with my poor hearing it seemed disturbingly loud. Any opinions welcome. John Roach N 2427H Yahoo! Groups Links
