TO ADJUST
CARBURETOR
(See
Fig.
35)
Tile carburetor has been present at the factory and adjust-
ment should not be necessary. However, minor adjustment
may be required to compensate
for differences
in fuel,
temperature, altitude or load, If the carburetor does need
adjustment, proceed as follows:
In general, turning the adjusting needles in (clockwise)
decreases the supply of fuel lo the engine giving a leaner
fuel/air mixture. Turning the adjusting needles out (coun-
terclockwise)
increases the supply of fuel to the engine
giving a richer fuel/air mixture.

DAMAGE TO THE NEEDLES AND THE
SEATS IN CARBURETOR
MAY RESULT IF SCREW IS
TURNED IN TOO TIGHT..
