I am having a problem with my BME 50 running right. It runs fine on the ground, but when you take the plane and point it up or in a knife edge condition it wants to run lean and die. I've tried about everything possable and was wondering if anyone had suggestions. I sent it to BME and they sent it back and said it was fine. I have it mounted inverted on a profile plane. I have tried ajusting the needles and also replaced the fuel tank. Any suggestions would be appreciated.

Thanks,
Charlie

Sounds as though you have a pump problem in your carb or the fuel line is restricted or sucking air from the tank?

It may be as simple as the filter screen in your carb is plugged with fuzz. Get to it from the pump side of the carb.
