1.5 turns for most carbs, but you can use a vacuum gage on the intake to get it right. Make sure engine is warm and on the regular idle screw, then turn the mixture screw in and then turn out until vacuum stops rising. OK?

There should be one screw (I'm assuming it's the Carter YF carburetor 1 barrel) that's by itself away from linkages etc, more to center at base of carb where it meets manifold, that is angled approx 45 degrees going in to base. That should be your mixture screw. What symptoms are you experiencing anyway?

The air screw and throttle screw are NEVER supposed to be tightened up at all. Doing this can damage the seat. Only screw the air screw and throttle screw in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Chances are you will need to replace the adjuster screws to get the bike to idle properly. Yeah, the ends look okay but that little ring indentation where the screw was tightened down matters a lot. If re-setting the screws fixes the problem you should consider yourself lucky.

Lightly seat the screws then open up each of them one and one half turns. This is the factory setting.
