float with the wire clip. The formed 90° lip
should point up, with the needle valve hanging
down. See Figure 5-29.
Figure 5-30. Installing Float Assembly.
14. Hold the carburetor body so the float assembly
hangs vertically and rests lightly against the fuel
inlet needle. The inlet needle should be fully
seated but the center pin of the needle (on
retainer clip end) should not be depressed. Check
the float height adjustment.
NOTE: The inlet needle center pin is spring loaded.
Make sure the float rests against the fuel inlet
needle without depressing the center pin.
15. The correct float height setting is 17 mm
(0.669 in.) ± 1.5 mm (0.059 in.) , measured from
the float bottom to the body of the carburetor.
See Figure 5-31. Replace the float if the height is
different than the specified setting. Do not
attempt to adjust by bending float tab.
