Mark, Since you have always had a problem with mixture in flight and none on the ground in static mode you might want to check your fuel vent location and make sure it is in positive air while in flight and not creating a neg. pressure due to slipstream around it.

If I didn't have it set in that magic spot I may get a slight hiccup. It's never that sensitive on the ground though as I can do a full static runup (3000 rpm) on the ground while never missiing a beat while playing with the mixture.
