Default RE: TT Pro 40 engine problems

I think that the engine might still be a little bit lean. Is it extremely hot when it shuts down?

I see a lot of guys at my field peak their engines on the ground thinking that they're getting the most out of them. They reject the explanation that the engine will unload in flight and, if already peaked on the ground, will lean out and die. Try the pinch test before you launch again - i.e., just a momentary pinch of the carb line. If you don't get a noticeable increase in RPM then you're still set too lean.

Just my $.02
