Answer Hi Rich,
Sorry for my delay. The holiday was busy.
The high speed mixture screw is initially set at 1&1/2 turns out. Then adjust it to give good acceleration and top speed while keeping the screw as far out as possible. The low speed mixture screw is set at 3/4 turn out, then adjust to give a smooth idle.
