I flew it today, and the needle valve position is very touchy. I had four engine quits after ~3 to 4 minutes. It has a new tank with new filters in the fuel line and fuel jug. I just put in new bearings, cleaned the carb and new gaskets along with the pump parts. I put in a new glow plug, but it still quit. I am using the Fox(miracle) glow plug. The motor quiits at ~1/3 to 1/2 throttle. I was using a 11/7 prop.

Thank You
