Inspection

1. Clean all carburetor components in suitable solvent and dry with compressed air. Be sure to blow out all carburetor passages completely.
2. Inspect air horn, main body and throttle body for cracks or other damage.
3. Inspect choke shaft and throttle shaft for wear.
4. Inspect air bleeds and jets for restrictions. If any restrictions are evident, clean in solvent and dry with compressed air. Air bleeds and jets must never be cleaned using wire. A wire may enlarge the hole or passage, adversely affecting carburetor performance.
5. Inspect pump piston cup for wear or damage.
6. Check accelerating pump check valve for proper operation.
7. Check power valve piston, if equipped, for proper operation.
8. Inspect float needle and seat for wear and the float for damage.

10. Inspect mixture adjusting screw for burrs or ridges.
11. Check for continuity between coupler and choke heater ground with an ohmmeter and replace choke heater if no continuity exists.
12. Check solenoid operation by connecting solenoid to 12 volts. When current is applied to solenoid, valve stem should be pulled into valve body.
