my 1996 AC EXT 580 is running a little rough. I think i need to adjust the carbs. First question does anyone know the proper setting for the air mixture screw? is it 1 turn from full in?
Second question is i can get my hands on a carb sinc gage. are these easy to use? and does anyone have some hints?

Thanks
:confused:

It is indeed one turn out, that's a starting point. A carb sync guage is easy to use, but the easiest way to sync them is to take the airbox off and put a finger on each slide. Slowly pull the throttle and make sure they start to move at exactly the same time. If one moves first loosen the cable on the top of that slide (turn it in) a little at a time until they open together.
