Get a vacuum gauge, attach it to a good vacuum port. Turn in air, and fuel bleeds in all the way( one is air, one is fuel), then backout 2 turns each. This is your starting point. Start engine, and slowly turn either the fuel or air bleed ( one at a time) untill the vacuum gauge reads the highest. Then do the same with the other bleed. You may have to turn down your idle screw a little as your idle will climb. This is the easiest and best way to adjust your air/fuel bleeds.
