Installation Guide

1. Safety First: Disconnect the battery and ensure the engine is cool. Work in a well-ventilated area and have a fire extinguisher nearby.
2. Remove the Carburetor: Disconnect the fuel line, throttle linkage, and any other connections. Remove the mounting bolts and carefully detach the carburetor from the engine.
3. Disassemble the Carburetor: Place the carburetor on a clean workbench. Carefully remove the screws to separate the bowl from the main body.
4. Remove Old Components: Take out the old float, float valve, gaskets, and seals. Note their orientation for correct reassembly.
5. Clean All Parts: Thoroughly clean the carburetor body, bowl, jets, and passages with a dedicated carburetor cleaner. Ensure all old gasket material is removed.
6. Install New Components: Install the new float valve and seat from the kit. Place the new gaskets in their channels.
7. Install the Float: Attach the new float assembly, ensuring it moves freely without binding. Check the float height and adjust if necessary, following your engine's service manual specifications.
8. Reassemble the Carburetor: Reattach the carburetor bowl, ensuring the gasket is properly seated. Tighten the screws in a crisscross pattern to ensure an even seal.
9. Reinstall Carburetor: Mount the reassembled carburetor back onto the engine. Reconnect the fuel line, throttle linkage, and any other connections.
10. Test for Leaks: Prime the fuel system and carefully inspect for any fuel leaks around the carburetor.
11. Start and Adjust: Start the engine and let it warm up. Adjust the idle speed and mixture screws as needed for smooth operation.

Troubleshooting & FAQ

How do I confirm this kit fits my engine?
First, check the "Part Number Cross-Reference" table to see if your old part number is listed. Second, review the "Compatible Engine Models" table to ensure your engine's horsepower, year, and model are included. Verifying both is the best way to ensure a match.

What are the common signs that a carburetor rebuild is needed?
Symptoms include difficulty starting, rough idling, stalling at low speeds, engine hesitation or sputtering during acceleration, and visible fuel leaks from the carburetor body.

Do I need one kit per carburetor?
Yes. This kit is designed to service a single carburetor. If your outboard engine has multiple carburetors, you will need to purchase one kit for each to ensure a complete and balanced repair.
