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.
