Default RE: Nitro models pusher Bobcat?
ORIGINAL: mkndls40

I have just finished assembling one of these with a gms 76, a pitts muffler and 11X7 prop.
I just switched to the pusher prop and seem to have trouble keeping the engine running.
I cant get the needle valve set correctly before the engine starts cutting out.
Seems to be overheating. Engine runs great with a regular prop on it (problem is it would fly backwards) hense the pusher prop...
any suggestions?
What is the history on the engine is it possible it is not completely broken in yet? Sounds like the case to me, these symtoms match up with that diagnosis perfectly.
