Figure 5-9. Proper Float Level.
6. Turn the carburetor body upside down and check
the float level as shown in Figure 5-9. With the
float needle valve fully seated, 16.5 mm (0.65 in.)
should be measured from the body to the float as
indicated. Don’t attempt to adjust by bending the
tab; replace the float with a kit if the level is
wrong.
7. Pull the float hinge pin and remove the float with
the inlet needle attached to inspect the needle and
seat. If dirty, blow out with compressed air.
Replace the float components as needed with the
kit.
8. Using new gaskets, reinstall the bowl and tighten
the bowl retaining screw or solenoid to
5.1-6.2 N·m (45-55 in. lb.).
9. Reinstall the carburetor on the engine, reconnect
the fuel line, control linkages and air intake
components. Retest operation.
