2. Shut Off Fuel: Turn off the fuel valve and safely disconnect the fuel line from the carburetor. Be prepared for minor fuel spillage.

4. Disconnect Linkages: Carefully disconnect the throttle and choke linkages. Note their original positions for reassembly.
5. Remove Carburetor: Unscrew the mounting bolts holding the carburetor to the engine and remove it.
6. Disassemble Carburetor: Place the carburetor on a clean workbench. Carefully disassemble it, starting with the float bowl. Lay out parts in order.

Troubleshooting & FAQ

Q: How do I know if this kit fits my specific Yamaha F4 model?
A: The best way to confirm is to check the Compatible Engine Models table on this page. Match your engine's model, horsepower, and year. You should also verify your existing carburetor's OEM part number against our Part Number Cross-Reference table.

Q: Why are there three different sets of package contents listed?
A: Yamaha updated the carburetor design for the F4 series over its production run. This resulted in three different repair kits (67D-W0093-00-00, 67D-W0093-01-00, and 6BX-W0093-00-00) for different model years. Our kits are matched to these specific OEM versions to ensure you get the correct parts.

Q: What are common signs that my carburetor needs to be rebuilt?
A: Symptoms include difficulty starting, rough or unstable idling, stalling at low speeds, engine hesitation upon acceleration, black smoke from the exhaust, and visible fuel leaks from the carburetor body.

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?
A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details.
