Cleaning & Inspection

1. The following components should not be immersed in carburetor cleaner:
a. Rubber or plastic components such as diaphragms, bushings, float, etc.
b. Idle speed solenoid, MC solenoid, SSC actuator and throttle position sensor.
c. Filters, gaskets and seals.
2. Thoroughly clean all metal components, ensuring that all passages are free from obstructions and contaminants. Clean pump diaphragm assembly in clean gasoline, but use only a suitable shop rag to clean diaphragm.
3. Blow dry all passages in castings with compressed air. Do not pass drills or wires through calibrated jets or orifices. Take care not to damage plastic feedback idle needle sleeve in air horn during cleaning.
4. If flooding was encountered prior to disassembly, inspect float, float arm and hinge pin for distortion, binds and burrs. Check float for leaks and/or any reason for being being heavier than normal.
5. If hesitation was encountered prior to disassembly, inspect pump diaphragm for cracks, scores or excessive wear. Check pump return spring for weakness or distortion and pump passages and jets for dirt and improper seating of inlet or discharge check ball. Check pump linkage for excessive wear.
6. If hard starting and poor cold operation were encountered prior to disassembly, check choke valve and linkage for excessive wear, binds or distortion. Check choke vacuum diaphragm for leaks and replace fuel inlet filter. Inspect inlet needle and seat assembly for sticking and dirt. Check fast idle cam for wear and damage.
7. If poor performance and poor gas mileage were encountered prior to disassembly, check mixture control solenoid for dirt, sticking, binding, damaged parts or excessive wear.
8. If rough idle was encountered prior to disassembly, inspect idle mixture needle for ridges, burrs or for being bent. Check gasket mating surface for damage to sealing beads, nicks and burrs. Check throttle lever and valves for binds, nicks or other damage. Clean passages at top of mixture control solenoid.
9. Inspect air horn and carburetor body for damage, distortion, burrs and excessive wear.
10. Inspect all components for burrs, damage and excessive wear or distortion.
11. Replace any component found defective.
