    At an idle can you turn them all the way in till they seat, and the motor continues to run? Call me curious.

    If your idle screw on your throttle arm has the throttle plates opened past the idle transfer slots, then your mixture screws won't have an effect when adjusted. Something you might look at!

    Check what TS said, if that's not the problem, the idle mixture screw seats, are ruptured. Probably time for a new carb. I don't know of any way to fix that.
