6. Remove the accelerator pump cover screws
(10) and accelerator pump cover (11).
7. Remove the U-ring (12), O-ring (13), spring
(14) and diaphragm (15).
Clean the diaphragm.
When installing the U-ring into the accelerator
pump cover (11) make sure the U-ring flatside
faces the accelerator pump cover, away from
the float bowl (16).
8. Remove the holder screw (17), throttle stop
screw holder (18), float bowl screws (19), hose
guides (20), float bowl (16) and O-ring (21).
9. Remove the pump rod (22).
Clean the pump rod and rod passage (23).
Install the pump rod by pushing the rod
forcibly into the link lever (24) until it snaps
into place.
10. Measure the float level (25) with the float level
gauge (26) while the float tab is just contacting
the float valve and the carburetor intake (27) is
facing up. The float level should be 0.28 in
(7.0 mm). If the float level is out of
specification, adjust it by bending the float tab
carefully.
11. Remove the leak jet (28) from the float bowl
(16). Clean the leak jet.
