Installation Guide

1. Safety First: Disconnect the battery and ensure the engine is cool. Turn off the fuel supply and safely disconnect the fuel lines from the carburetor.
2. Removal: Carefully remove the airbox cover and filter. Label and disconnect any vacuum lines or linkages, then unbolt and remove the carburetor from the intake manifold.
3. Disassembly: Working in a clean area, disassemble the carburetor. Start by removing the float bowl to access the internal components.
4. Cleaning: Thoroughly clean all metal components with a quality carburetor cleaner to remove varnish, gum, and dirt. Ensure all jets and passages are clear. Warning: Do not use cleaner on rubber or plastic parts.
5. Component Replacement: Carefully replace the old gaskets, seals, O-rings, needle valve, and float assembly with the new parts from the kit.
6. Reassembly: Reassemble the carburetor in the reverse order of disassembly, ensuring all screws are properly torqued and floats are set to the correct height.
7. Reinstallation: Mount the rebuilt carburetor back onto the engine, reconnecting all fuel lines and linkages. Reinstall the airbox.
8. Final Adjustments: Turn the fuel supply on and check for leaks. Start the engine and adjust the idle speed and air/fuel mixture screws as needed for smooth operation.
