Installation Guide

  1. Safety First: Before starting, disconnect the battery and fuel lines to prevent accidents. Work in a well-ventilated area.
  2. Remove Carburetor: Carefully detach the carburetor from the engine, taking note of all linkage and hose connections.
  3. Disassemble: Place the carburetor on a clean workbench. Systematically disassemble it, laying out all parts in order to ensure correct reassembly.
  4. Clean Components: Thoroughly clean all metal components with a quality carburetor cleaner to remove varnish, grime, and deposits. Do not use cleaner on non-metal parts.
  5. Replace Parts: Install the new gaskets, O-rings, and seals from the kit. Ensure all surfaces are clean and dry before installing new gaskets.
  6. Install Needle & Seat: Carefully install the new needle valve and seat assembly. This is critical for proper fuel flow control.
  7. Install Float: Attach the new float and verify its height is set to your engine's specifications. Proper float level is essential for engine performance.
  8. Reassemble Carburetor: Carefully reassemble the carburetor, referring to your notes or a service manual to ensure all parts are correctly placed.
  9. Reinstall Carburetor: Mount the rebuilt carburetor back onto the engine and reconnect all linkages and fuel lines.
  10. Final Checks: Reconnect the battery. Start the engine and carefully check for any fuel leaks. Let the engine warm up and adjust the idle mixture and speed screws as needed.

Troubleshooting & FAQ

Q: How do I confirm this kit fits my specific engine model?

A: The best way is to match your engine's original part number to the numbers listed in our "Part Number Cross-Reference" table. You should also check your engine's horsepower and year against the "Compatible Engine Models" chart to ensure it falls within the specified range.

Q: What are common signs that my carburetor needs to be rebuilt?

A: Symptoms indicating a needed rebuild include difficulty starting the engine, rough or unstable idling, stalling at low speeds, hesitation or bogging on acceleration, and excessive black smoke from the exhaust, which can indicate a rich fuel mixture.

Q: Is it necessary to replace the float when rebuilding the carburetor?

A: Yes, this kit includes a new float and it is highly recommended to replace it. Over time, original floats can absorb fuel, develop pinhole leaks, or degrade, which alters the fuel level in the bowl and can cause persistent flooding or starving issues.

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. Returns are accepted within our standard return window (unused & in original condition); please see our policy page or reach out for instructions.
