Does operating an engine inverted require any different settings than if it is tweaked "right side up"? I'm guessing generally the carb would be a lower than the tank. Running a Pico .46 in an Altech "Tamecat". Runs fine everywhere but has a tendency to "flameout" on climbout? If I turn the plane up-side down and tweak the settings, I am more likely to cure the problem or make it worse? What about 4 s's,any difference there. Maybe there's an older thread that addresses this issue.
