SSD,
(normal carbs - like that fitted to the Chipmink - will cease to function when inverted).
Interesting this, and it could explain something for me. Recently, whilst making a fairly lengthy series of very steeply banked turns over a point on the ground, the engine in my 172 "coughed" a couple of times (swiftly followed by my bottom, but that's another story

). Wings level, full power climb, away we went no problem.
I know this wasn't carb-ice related, I'd been taking care of that carefully. So could this have been carb-related ? What angle would you have to bank to to cause problems with a standard carb ?
