#3 and #4 carbs on my '82 GW have these screws with a little tabs on them, I assume for turning. Are these the idle mixture screws? How come #1 and 2 don't have them?

Thanks
Brian

All four carbs have them. The caps may be removed from the other two revealing brass screw heads or someone may have broken the screw heads off entirely.

those tabs are to limit the adjustment , ONCE it`s set. (factory)
