Figure 5-16. Checking Float Height.
7. 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.
8. 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 5-16. Replace the float if the height is
different than specified.
DO NOT
attempt to
adjust by bending float tab.
NOTE
: Be sure to measure from the casting
surface, not the rubber gasket, if still
attached.
9. When the proper float height is obtained,
carefully reinstall the fuel bowl onto the
carburetor, using new O-Rings. Secure with the
four original screws. Torque the screws to
2.5 ± 0.3 N·m (23 ± 2.6 in. lb.)
. See Figure 5-17.
Figure 5-17. Installing Fuel Bowl.
10. Install the carburetor and reassemble the engine
as outlined in Section 10 Reassembly.
Disassembly/Overhaul
1. Clean the exterior surfaces of dirt or foreign
material before disassembling the carburetor.
Remove the four mounting screws and separate
the fuel bowl from the carburetor. Transfer any
remaining fuel into an approved container.
Remove and discard the old O-Rings. Fuel can
also be drained prior to bowl removal by
loosening/removal of the bowl drain screw. See
Figure 5-18.

NOTE
: Further disassembly of the fuel bowl is
not necessary unless the Fuel Solenoid
Kit, or Fuel Bowl Kit (obtained
separately), will also be installed.
