what exactly is the proper way to set the floats and idle mixture (i.e rich/lean) settings on a 650 double pumper carb?

Contact Earl Parker (www.parkercarburetion.com) He is, I think, in NC.

Earl is the man but I'll through my pennies on the floor too. You want the floats set where the fueljust barely dribbles out of the sight plugs while the motor is running. As far as rich/lean here is my method. Turn the screws in all the way until they SOFTLY bottom out. Back them all out 1 and 1/2 turns. Crank it up and adjust one at a time starting in the front while looking for the highest vaccum reading. After you have done all of them reset your idle and do it again.
