necessary. However, minor adjustment
may be required to compensate for
differences in fuel, temperature, altitude or
load. If the carburetor does need adjust-
ment, proceed as follows:
In general, tuming the mixture screw In
(clockwise) decreases the supply of fuel to
the engine giving a leaner fuel/air mixture.
Turning the mixture screw out (counter-
clockwise) increases the supply of fuel to
the engine giving a dcher fuel/air mixture.
IMPORTANT: Damage to the needles and
the seats in carburetor may result if screw
is tumed in too tight.
