Cleaning & Inspection

1. Clean components with suitable solvent and blow dry with compressed air, noting the following:
a. Do not immerse micro switches, solenoids, float, accelerator pump plunger, diaphragm capsules, choke thermostat, gaskets or seals in carburetor cleaner, as they will be damaged.
b. Ensure that dirt, solvent and all foreign material is removed from casting passages and calibrated orifices. Do not insert drills or wires into fuel passages, jets or air bleeds as they will be damaged.
2. Check continuity and operation of solenoids and replace as needed.
3. Check diaphragm capsules for damage and leaks, and replace as needed.
4. Check choke and throttle valves for free operation, damage and looseness. Screws securing choke and throttle plates are staked to prevent loosening. Do not remove screws unless plates or operating shafts must be replaced. If replacement is required, ensure that new screws are properly installed and staked to prevent loosening.
5. Inspect accelerator pump piston and replace if rubber cup is damaged or deteriorated.
6. Inspect MC solenoid seal and replace as needed.
7. Inspect needle valve and seat and replace if worn, grooved or damaged.
8. Inspect float for fuel saturation, wear and damage.
9. Replace body casting if worn, distorted or damaged.
10. Replace all gaskets seals and linkage retainers during assembly.
