Mid range seems lean. Idle ok, top end good. 1/4 to 1/2 throttle seems to lean out, rpm will go up and down, smoke will come and go with rpm. I have low needle 1 turn out, high speed 1 1/2 turns, regulator about 1 turn out from flush. Seems to get better as I go out with regulator, if I go in from flush with reg, idle will start to go up and down too.
Am I going the right way with this? Fuel 30% Omega helli.
Prop 11-7. I have about a gallon threw this and only about 30 min flyeing because I cannot get the engine to run right.
This is my first YS motor and any help will be greatly appreciated.

Thanks:
