Screw the main jet in until seated then 4X out.
Screw in idle jet until seated then out 2X.

With warm or hot engine and at idle;
Goose the engine. Main jet in until black smoke, then out till engine runs smooth. Adjustment will be between the two.

Retard the spark until engine about dies, then screw in idle jet until runs better.
