Hi


Flew my WH Ultimate and DA50 today, now this engine has had about 2 gall through it now and needles have been adjusted to give good transition, and slightly rich top end.

But i still get a popping sound at 1/4-1/2 throttle and it seems as if the engine misses a beat now and again, only when below half throttle (low needle) is it still too rich?? even though transitions good most of the time?

I am using Belray HR1 at 50-1. 22x8 Menz prop


Thanks
