I have an OS 61FX. I have run 1 gallon of fuel thru the engine at a rich setting, which was 2 turns of the needle valve. (After flying, the fuse and stab were fuel SOAKED). I have read the manual and I guess I'm kinda confused. This is my first engine (I'm still new at this hobby). What is the correct procedure to know that your engine is properly leaned out?


I am using 15% Nitro. I came home and turned my needle valve down to only a half turn from closed, It is still cool enough to touch, but I just dont want to damage it.


Any advice would be great.


Thanks
