Can anyone tell me the factory setting for the mixture control needle valve on an OS 32SXH,... I ran it today in the heli and had really good smoke and the highspeed needle valve was 2 turns out for starters.

After flying, I looked at the engine and you could smell the heat... it was way too hot and had that "Lean" smell to it. So if anyone can tell me a good setting to set it at I sure would appreciate it, especially the low end, (mixture) setting. It's at 3 turns out now.

The high needle is set to 1&1/2 turns from fully closed. To set the low needle screw back to the factory setting the manual states to look down the carb and line up the shoulder portion of the valve to be tangent with the throttle rotor hole. It will be easier to understand this looking at the sketch thats in the manual. Maybe someone can explain it better or tell you where to go for help.
