[cab]

with my center shaft connected and my pass. Side idle backed out and driver side idle screw turned in to keep rpm up a little say 1000 to 1500 I have my air screws 1turn out ,I know every one will tell you 3/4 but this works for me.I start in the drivers side and turn the screw between the back and front carb, the numbers should start to come together it my take a few turns on the 2center carbs then I do the other side ,now you might have different no" side to side at this point, but then you can pull them together with the center shaft ,idle will change once the no# are the same set idle. Turn off and tighten center shaft.mine as done the same as yours ...
