Throttle Lever
Remove the throttle lever and spring and file off the peened end of the throttle shaft until the lever can be removed. Install
the throttle spring and lever on the new carburetor with the self-tapping screw furnished. If dust seals are furnished,
install them under the return spring.
Idle Speed Adjustment Screw
Remove the screw assembly from the original carburetor and install it in the new carburetor. Turn it in until it contacts the
throttle lever. Then an additional 1-1/2 turns for a static setting.
Final Checks
Consult the service section under “Pre-sets and Adjustments” and follow the adjustment procedures before placing the
carburetor on the engine.
