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.   

Good Luck.
Michael
