I am wondering out loud if anybody has ever made an aero rotary run on a gravity feed carb.

Ahhhh, Now I get it !

Yes, Andy Veneble had a Marvel Scumbug (sp ?) updraft tractor/airplane carburetor on his Mazda rotary engine.   His engine siezed - oil problem I guess, and he replaced it with a Franklin airplane engine of 200 hp  His bird is a high wing Christavia.

So it can work.  Andy had his motor set in the plugs-up orientation, to avoid the complication of the exhaust or wrap around the whole motor.  Your idea of mounting the carb in front of the engine might be a winner, if you have the room.

If you look at the pictures of the Corvair powered airplanes, the intake route looks long and complicated, yet they fly. They probably need a primer pump with injectors near the intake valves to get started (my conjecture).
