  3. Disassemble the carburetor on a clean surface. It's helpful to take photos during this process for reference.
  4. Remove old gaskets, seals, and o-rings. Thoroughly clean all metal parts with a quality carburetor cleaner, ensuring all passages are clear. Do not use cleaner on non-metal parts.
  5. Carefully install the new components from the kit, ensuring each part is seated correctly.
  6. Reassemble the carburetor, comparing against your photos to ensure accuracy.

Troubleshooting & FAQ

Which Johnson/Evinrude engines does this kit fit?

This comprehensive kit is designed for a variety of 2-stroke Johnson/Evinrude outboard motors, including 4, 4.5, 5, 6, 7.5, 8, 9.9, 14, and 15 HP models, generally from years 1974–1993. Because fitment can be specific, it is essential to check your engine model and year against the compatibility table provided on this page.

Does this kit include the carburetor float?

No, the float is not included in this rebuild kit. The float is a durable component that often outlasts other parts. If your float is damaged, saturated, or needs replacement, it must be purchased separately. See Sierra part number 18-7210.

My carburetor part number isn't 398453. Can I still use this kit?

Yes, possibly. This kit serves as a replacement for multiple OEM and aftermarket part numbers. Please check the Part Number Matrix on this page to see if your carburetor's part number is listed as an equivalent cross-reference.

What are the signs that my carburetor needs to be rebuilt?

Common symptoms of a failing carburetor include difficulty starting the engine, rough or unstable idling, stalling at low speeds, bogging down during acceleration, increased fuel consumption, or black smoke coming from the exhaust. These issues often point to clogged passages or degraded seals inside the carburetor.

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?
