Bill,
Thanks for the advice.
I started to slightly lean it out today. I ran it up to half throttle and it read about 6000 rpm on my tach. I leaned the high speed about 1/4 turn and the rpm increased about 300-500 rpm. This motor puts out a ton of prop wash. I used to .40-.50 size motors.
I thought it would be harder to tune than my 2-strokes, but aside from messing up the timing myself, I have had no problems. Saito's are freaking awesome. I don't know why I waited so long to get into 4-strokes.
Thanks again.
