What About OS 2 Stroke Engines? I have 13 of them and Run Coll Power 15% that I add 4 oz of Klotz Caster Oil to a Gallon of fuel. I'm learning 3D now and have mostly 3D Capable Birds. Engines from 46FX to 120AX and all but new 75AX. I try keep My Engines on Slightly Rich Side or 200 RPM to 300 RPM less Peak RPM when setting Main Needle Valve. Any advice for Retired Disabled Veteran? richgrow
