Hi Brent,
ok, I'll check again and watch the valves.
Wich Timing will be the best at 900 rpm idle for that engine ? I normally set them to 16° BTDC at idle. 32° at full advance.
Best,
Stephan
That’s a pretty good place to start. It may want 34-36 total.
Usually a backfire out carb is retarded ignition timing so I think what I suggested will work. Make sure you check the power valve in the carb to make sure it’s not blown.
