Installation Guide

2. Carefully remove the air silencer cover and base to access the carburetors.
3. Note the linkage and hose connections, then remove the carburetors from the intake manifold.

5. Remove the float bowl, float, pin, and needle valve assembly. Discard the old gaskets, seals, and O-rings.
6. Clean all metal components with a quality carburetor cleaner. Ensure all jets and passages are clear of debris.
7. Install the new components from the kit, including the needle valve, gaskets, and O-rings.
8. Set the float height to the manufacturer's specification. Reassemble the carburetor carefully.
9. Repeat the process for the remaining carburetors.
10. Reinstall the rebuilt carburetors onto the engine, reconnecting all linkages and fuel lines securely.
11. Check for any fuel leaks before starting the engine.
12. Start the engine and adjust the idle and pilot screws as needed for smooth operation.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my Yamaha engine?
A: The best way is to match your engine's model and year to our compatibility chart. For Yamaha engines, you can use the linked guide to find your serial number, which helps confirm the exact model and production year. Verifying the OEM part number (6H3-W0093-01-00 or its successors) for your specific engine is the most reliable method.

Q: What are the signs that my carburetor needs rebuilding?
A: Common symptoms include difficulty starting, rough idling, stalling at low speeds, poor acceleration, or black smoke from the exhaust. Fuel leaks from the carburetor body are also a clear indication that the seals have failed and a rebuild is necessary.

Q: My Tohatsu model is listed, but the year range is not specified. How can I confirm fitment?
A: If your Tohatsu model (e.g., M30A4, 60C) is listed, this kit is documented as compatible. The primary cross-reference is the OEM part number 346-87122-0. If your existing carburetor parts match those shown in the images and your service manual calls for that part number, this kit should fit.

Q: OEM vs. Aftermarket?
A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

Q: How fast do you ship and how much does it cost?
A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.

Q: What is your warranty and return policy?
