Installation Notes

  1. Disconnect the fuel line and disconnect the battery for safety.
  2. Remove the engine's outer cowling to access the carburetor.
  3. Carefully note and detach any linkages (throttle, choke) and fuel hoses connected to the carburetor.
  4. Unbolt and remove the carburetor from the intake manifold.
  5. Disassemble the carburetor on a clean, organized surface. An exploded diagram from a service manual is highly recommended.
  6. Thoroughly clean all non-wear metal parts with a quality carburetor cleaner spray. Avoid soaking any rubber or plastic components.
  7. Systematically replace the old gaskets, seals, needle, and seat with the new components from the kit.
  8. Reassemble the carburetor, ensuring all parts are correctly seated and screws are tightened to the manufacturer's specified torque.
  9. Install the rebuilt carburetor back onto the engine, reattaching mounting bolts, linkages, and hoses.
  10. Prime the fuel system and carefully check for any leaks before attempting to start the engine.

Troubleshooting & FAQ

How do I know if this carburetor kit fits my engine?

The best way to confirm is to match your engine's model, horsepower, and year to the compatibility table. Also, cross-reference your existing carburetor's part number with the numbers listed in our Part Number Matrix.

What are common symptoms that this rebuild kit can fix?

This kit can resolve issues like poor idling, engine stalling, hesitation on acceleration, fuel leaks from the carburetor body, and hard starting, which are often caused by degraded internal gaskets, seals, or a clogged needle valve.

Does this kit include the carburetor float?

This is a standard rebuild kit and typically includes gaskets, seals, and the needle/seat assembly. It does not include the float or other hard parts unless specified in the "What's in the Box" section. Floats are generally replaced only if they are damaged or saturated with fuel.

How often should an outboard carburetor be rebuilt?

There is no fixed interval. It depends on usage, fuel quality, and storage conditions. If you notice performance issues or after a few seasons of use (especially with ethanol-blended fuels), a rebuild is good preventive maintenance.

My engine still runs poorly after the rebuild. What did I miss?

First, double-check for any vacuum leaks around the carburetor base gasket. Ensure the float height is set correctly as per your service manual's specifications. Clogged fuel passages that weren't cleared during cleaning can also cause issues. Finally, the problem might lie elsewhere in the fuel or ignition system.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.

Shipping speed & cost?

We ship worldwide quickly—typical transit 5–15 days. Standard shipping is free; expedited options appear at checkout where available.

Warranty & returns?

Covered by a 1-year warranty against manufacturing defects under normal use. If issues arise, contact support with your order details. Returns are accepted within our standard window (unused & in original condition). See our policy page or reach out for instructions.
