Easiest way to start is to back the idle screws off completely... then turn till they just touch... then go about two turns. Start and warm engine... set idle by turning each up or down equally until you get the idle speed you want... then hook up the linkage and adjust it so it does not push or pull the throttle, but goes straight on to both carbs.
It's not the dead nuts method... but it's the get you pretty damn close for a beginner method.
I start this way, then go to balancing out based on how each pulls vacuum by ear... or unisyn if it will fit... but like I said... the other way will get you pretty damn close.
