Assemble Carburetor

1.Install new welch plug with pin punch of slightly smaller diameter than the plug. Press against the plug until it is flat in the carburetor opening. Do not cave in the plug. Seal the edge of the plug with a non- hardening sealant.

2.Reinstall main jet and seal

3.Install new seal and spring on the choke shaft with the top of the spring contacting the choke shaft lever (B, Figure 63).

6.Insert the choke plate into the choke shaft with the dimples toward the fuel inlet side of the carburetor. Dimples center the choke plate on the shaft (A, Figure 65).

Figure 63

4.Turn the choke shaft counterclockwise while gently pushing it into the carburetor body until the bottom end of the spring (D) rests on the back of the spring perch (A).

5.Lift the choke shaft up slightly and continue turning counterclockwise until the stop on the lever clears the spring perch. Push the shaft inward. When released, the choke shaft lever should rest on the spring perch as shown (Figure 64).

7.Install foam washer (B) to throttle shaft (A, Figure 66). Install throttle shaft to the carburetor body. Turn throttle shaft until flat is facing out.
