adjustment, proceed as follows:
In general, turning the mixture screw in (clockwise) de
creases the supply of fuel to the engine giving a leaner fuel/
air mixture. Turning the mixture screw out (counterclock
wise) increases the supply of fuel to the engine giving a
richer fuel/air mixture.

SEATS IN CARBURETOR MAY RESULT IF SCREW IS
TURNED IN TOO TIGHT.

closing it finger tight and then turn out (counterclock
wise) 1-1/4 to 1-1/2 turns.

final adjustments with engine running and shift/ motion
