My T sometimes backfires when I shut it off any ideas why ? Thank you for any and all advice.
May have a warped/burnt exhaust valve
Describe your shut down procedure. Do you idle down and return the levers to the start position or something else ?
Close the throttle completely and let the engine slow down to idle speed with throttle closed before shutting off the ignition. The engine spinning faster than idle (especially with throttle set at anything over idle position) tends to fill the exhaust pipe/muffler with unburned gasoline vapor because the engine quits burning the mixture as soon as ignition is shut off. The mixture then flows into exhaust and is ignited (as in BOOM) by a hot spot in exhaust system.

Thank you for the info. I will try that next time. Shutting down the idle first.
