Installation Guide

1. Before you begin, ensure the engine is off and cool, and the fuel supply is shut off.
2. Carefully remove the air silencer and disconnect the fuel lines and any linkages from the carburetor. Remove the mounting bolts to detach the carburetor from the engine.
3. Disassemble the carburetor on a clean workbench, taking photos as you go to remember the order of parts. Pay close attention to small components like jets, screws, and springs.
4. Thoroughly clean all metal parts using a quality carburetor cleaner spray and a small brush. Ensure all passages and jets are clear of debris. Do not use cleaner on rubber or plastic parts.
5. Carefully remove the old gaskets, O-rings, needle valve, and float from the carburetor body.
6. Install the new components from the rebuild kit. Ensure the float height is set to your engine's specifications, which can be found in a service manual.
7. Reassemble the carburetor components in reverse order of disassembly.
8. Mount the reassembled carburetor back onto the engine, reconnecting all linkages and fuel lines. Reinstall the air silencer.
9. Turn the fuel supply back on and check for any leaks. Start the engine and adjust the idle and air/fuel mixture screws as needed for smooth operation.
