A CH 750 can't do rolls or loops, so, it's no problem for me. ;-)
The Bing has a float bowl, so I doubt it could handle inversion for any appreciable time. The AeroInjector for the 3300 is supposed to be good for short duration inversion and negative g maneuvers. Don't know about the Rotec carb.
Same here - have a STOL 750 so no aerobatics, but I do have a AeroInjector TBI carb on my 3300. Since it works best strictly gravity-fed, the mech. fuel pump is removed on my engine. When testing the carb, I did a series of push-overs stepping down from altitude and induced enough neg G's each time to lift me in my seat, but obviously could only sustain that for a few seconds at most with each push-over! However, the 3300 never missed a beat.
I happen to notice yesterday that the current Jabiru manual prohibits negative G maneuvers based on the oiling system. This is in the newest Generation 4 manual.
