MAINTENANCE
Carburetor/Engine Idle RPM Adjustment
2 Cycle Engines
If the engine idle speed is not satisfactory, and all other conditions
are favorable, the carburetor can be adjusted as follows:
1. Warm up the engine by
running the vehicle
approximately five min-
utes.
2. Place the transmission in
gear with the parking
brake applied.
3. Adjust the carburetor idle
screw in or out until the
desired idle RPM is
reached. Turning the
screw in (clockwise) will
raise RPM. Turning the
screw out (counterclock-
wise) will lower RPM.
The follo wing variations to air screw adjustment for 2-Cycle en-
gines should be noted:
D For improving cold weather start and reducing audible deto-
nation noise, the air screw can be closed from 1/2 to 1 turn
by turning the screw clockwise.
D During hot weather and/or high altitude operation the air
screw can be adjusted for smooth operation by approxi-
mately 2 turns counterclockwise.
