Hello everyone, I have a new, but three year old Rossi 45. I am using 10% nitro Omega fuel and using a APC 10x6 prop and an O.S. #8 glow plug. The engine is running great on top end.
However, it is loading up on the bottom end. The engine hesitates when I give it full throttle from idle speed, to the point it almost stalls. I have the low end needle valve screwed in almost all the way in. Does anyone out there know how to get this engine running right? I know that Rossi engines are suppose to run on fuel without nitro, but this type of fuel is not available in my area. Thanks for your help.
