4. Remove the two screws securing the top cover,

gasket, and ground lead (fuel solenoid-equipped

models). Discard the gasket and screws only.

5. Remove the idle speed and idle fuel adjusting

screws and springs from the carburetor. Discard

the parts.

2. Remove the float pin screw and lift out the old

float, pin, and inlet needle. See Figure 5-18.

Discard all of the parts. The seat for the inlet

needle is not serviceable, and should not be

removed.

Figure 5-18. Removing Float and Inlet Needle.

3. Remove and discard the round plug from the

bottom of the slow jet tower of the carburetor

body. Use an appropriate size flat screwdriver,

and carefully remove the slow and main jets from

the carburetor. After the main jet has been

removed, the main nozzle can be taken out

through the bottom of the main tower. Save the

parts for cleaning and reuse. See Figure 5-19.

NOTE: The carburetor is now disassembled for

appropriate cleaning and installation of

the parts in the overhaul kit. Further

disassembly is not necessary. The

throttle shaft assembly, fuel inlet seat,

and bowl chamber baffle, 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

24 757 36-S will be installed.

6. Clean the carburetor body, jets, vent ports, seats,

etc., using a good commercially available

carburetor solvent. Use clean, dry compressed air

to blow out the internal channels and ports.

Inspect and thoroughly check the carburetor for

cracks, wear, or damage. Inspect the fuel inlet seat

for wear or damage. Check the spring loaded

choke plate to make sure it moves freely on the

shaft.

7. Clean the carburetor float bowl as required. If it

has an accelerator pump that is not being serviced

at this time, prevent the cleaning solvent from

contacting the check valve and accelerator pump

components.

8. Install the main nozzle and the main jet into the

tower of the carburetor body. See Figure 5-20.

Figure 5-20. Installing Main Nozzle and Main Jet.

9. Install the slow jet and new plug into end of slow

jet tube. See Figures 5-21 and 5-22.
