Actually mine is running good now, Mine was definately going rich, I leaned it a little and it helped the inverted flight. Which carb are you using ?
Oh, and BTW, mine never sagged right side up, it ran fine at all RPMs, only inverted it was giving trouble.

Hey BBriBro, do you still have problems with your GX25 sagging at full throttle? Mine is doing that. It acts like it goes lean at full throttle. What I think is happening is that with the throttle all the way open there is not enough engine vacuum left to go through the little passage and make the diaphragm in the carby do its thing.
