Everything I have seen on tuning is making this process way to complicated. I can tune a .46FX so I'll tell you my very un-scientific method.

-First warm it up some.
-Open her wide up and richen(counter clockwise the high end needle) until it noticeably drops in pitch.
-Then lean until it picks up pitch. Go a couple of clicks past.
-Now let it idle down for 15 seconds or so. Give it full throttle.
-If it transistions poorly lean it out a 1/8 turn. Try again until it transitions well.
-If you think the low end is lean, richen until it transitions poorly then slowly lean until it transitions well.

I'm sure there are some probs with this but it is easy and works for me. No rocket science here.
