float, pin, and inlet needle. See Figure 5-19.
Discard all the old parts. The seat for the inlet
needle is not serviceable, and should not be

and reuse unless a Jet Kit is also being installed.
Clean the slow jets using compressed air. Do not
use wire or carburetor cleaner.

3. Use an appropriate size flat screwdriver, and
carefully remove the two main jets from the
carburetor. Note and mark the jets by location
for proper installation. The main jets may be
size/side specific. After the main jets are
removed, the main nozzles can be removed out
through the bottom of the main towers. Note the
orientation/direction of the nozzles. The end with
the two raised shoulders should be out/down
adjacent to the main jets. Save the parts for
cleaning and reuse. See Figure 5-20.

the parts in the overhaul kit. Further
disassembly is not necessary. The
throttle shaft assembly, fuel inlet seat,
idle fuel adjustment screws with limiter,
and carburetor body, are non-
serviceable items and should not be
removed. The choke shaft assembly is
serviceable, however it should not be
removed unless a Choke Repair Kit will
be installed.
