Check your fuel system, if the fuel foams or the center of the tank is off in relation to the center of the engine, that might be your problem. Dubb will tell you, as he did me, "95% of all engine run problems are in the fuel system. Do you know where the other 5% are? In the fuel system." He real specific about don't let the tank touch ANY part of the airframe, put foam around the tank.
Dubb, Bob, and Dennis have given me so much info that I could write a book, and guess what, it all works.
