Repair and Service Manual
Read all of Section B and this section before attempting any procedure. Pay particular attention to all Notes, Cautions and Warnings.
B
Fig. 4 Air Cleaner
Do not tamper with the pilot screw (7) or plastic cover.
Remove the pilot jet (8).
Wash all parts in solvent and blow through all passages
with compressed air. Replace all gaskets and any parts
which show significant wear or damage.
Float Level Adjustment
When adjusting the float,
never
bend the float arm, always
bend tang #1 (Ref. Fig. 6 on Page H-6).
Turn carburetor upside down. Remove the bowl. With
the carburetor inverted, the ‘B’ side top edge of a prop-
erly adjusted float will be slightly above parallel to the
bowl gasket surface and both sides of the float will be
level with each other (Ref. Fig. 6 on Page H-6). If the
sides of the float are not parallel or if the ‘B’ side of the
float is not slightly above parallel with the bowl gasket
surface (.030" -.060”) (.8 - 1.5 mm), an adjustment is
required. Adjust by inserting needle nose pliers into the
slot on the top of tang #1 and hold firmly while adjusting
the floats by gently lifting or pushing with the other
hand. Reinstall the bowl, copper gasket and the screw.
Check for fuel leaks.
After adjusting float level, reassemble the carburetor in
reverse order of assembly. The pilot screw is factory
set.
Check for free movement of the choke shaft before
installing the carburetor. Lubricate the bushings with
WD-40
®
oil or equivalent.
Throttle Shaft Adjustment
To adjust the throttle shaft (9) and throttle valve (10),
turn throttle stop screw (11) counterclockwise until it no
longer contacts tab on the throttle shaft (Ref. Fig. 5 on
Page H-5). Hold the throttle shaft in the closed position,
then turn the throttle stop screw clockwise until it con-
tacts the tab on the throttle shaft; turn the screw clock-
wise 1/4 turn.
Carburetor Installation
To prevent possible injury from explosion or
fire, check for clogged or kinked hoses.
Clogged or kinked carburetor hoses are not
only detrimental to the proper operation and
performance of the vehicle, but can also be a
safety hazard in the case of fuel leaking on a
hot engine
