      I’ve got a Mercury Mark 20H with the Carter Carb and I’m wondering where to start (how many turns out) on the high speed screw and Idle screw.  I believe the idle screw is the top on and the high speed screw is the bottom one and please correct me if I’m wrong.

      Thanks for any suggestions
