If you have the stock AFC spring, don't spin the star wheel all the way toward the engine. Just turn it some, say 5 or 10 clicks at a time. Well before the star wheel reaches the front of the hole where the plug goes, all tension on the spring will be relieved and smoke control will be very poor (without helping power any more). If you have the TST AFC spring, then start at or near the end of star wheel travel. I like about 5 clicks per 1000 ft elevation from the richest setting for the TST springs.
Put the afc full forward, and you can fine tune the start fuel before boost occurs with the stud at the back under the tin cover. usually you can get away wtih turning the stud until it contacts the link for the last 1/2 turn. and still keep smoke down.
