That's not really what I do. I just use the idle screws for a stable idle, starting around .75-1 full turn out. Balance using bypass screws. Then balance above idle using synch rod (1800-3krpm). Somewhere around 521mv is usually where you end up. Don't worry about that for now though. Good stable idle, well balanced, go for a ride. If you're happy congrats! If not try again, it took me a few tries the first time once you get it you'll be happy...
