Fig. 6 Carburetor Disassembly
Float Level Alignment
(Ref. Fig. 7)
The float level cannot be adjusted but should be inspected for
proper alignment (Ref. Fig. 7).
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. 7). 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 then the
float should be replaced. Reinstall the bowl, washer and
the screw. Check for fuel leaks.
Check for free movement of the choke shaft before
installing the carburetor. Lubricate the bushings with
WD-40

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 Air Cleaner
Do not let the carburetor vent hose become clogged or
kinked. Engine heat will cause the fuel in the carburetor
bowl to expand and may result in fuel being expelled from
the carburetor if unable to vent through the vent tube.
Replace carburetor in reverse order of disassembly. Use
a new gasket to ensure sealing of carburetor. Tighten
hardware to 50 - 70 in. lbs. (6 - 8 Nm) torque
(Ref. Fig. 5).
FUEL PUMP
The fuel pump is mounted on a bracket attached to the
seat support near the gasoline tank on the passenger
side and is operated by crankcase pressure impulses
from the engine. As the piston moves up in the cylinder,
a negative pressure moves the diaphragm within the
