Tim I was wondering if i could get your opinion on the method I was taught to tune the YS idle needle.

Find the needle setting were the engine RPM peaks. So i VERY SLOWLY lean the idle screw, the RPM will continue to increase. I make sure to do this very slowly, sometimes I will have to adjust my throttle trim (a sign that it was too high to begin with). Eventually I will find a point that if I continue to lean the idle needle the RPM will actually drop. The needle setting where it peaked is my peak RPM point. I then add 1/8th turn to richen up the idle needle.
