The 1 to 1-1/2 turns is really just an approximation or a starting point for adjusting idle mixture. Adjustment is best done with a vacuum gauge, setting for maximum vacuum consistent with not extending the mixture screw any further outward than that point.
I'd need a picture of the other adjustment screw, and there is no external high speed mixture adjustment. Is the screw just the idle speed adjustment?
I've got the idle mixture adjustment at about 1.25 turns, which seems about right. I might fiddle a bit with it. Enriching it increases idle RPM, leaning decreases it (obviously) so there's also balancing out the idle speed with the throttle set screw.
No, the other mixture screw is probably not another idle mixture adjustment. I don't want to touch it, because I don't know what it does.
I don't have a pic of the set screw on the right of the throttle body (as you face the carb), but can get one if nobody out there knows about this screw on the 2-barrel Carter WGD 2102S.
I give the model number because I don't think it's the exact same carb as the regular WGD. In the shop manual, the number is specific to the '54 2-barrel. There is no number given on the earlier WGD 2-barrel carbs, nor in the section in the manual on re-building and setup--it's just called WGD. Nothing additional info or supplement for the WGD 2102S.
