Troubleshooting & FAQ
How do I know if this float valve fits my engine?
This part fits many Johnson/Evinrude V4 and V6 crossflow looper engines. The best way to confirm is to match the OEM part number 0387262 or 387262 from your engine's service manual or by visually comparing it to your existing part.
What are signs of a failing float valve?
Common symptoms include fuel leaking from the carburetor (overflowing), the engine flooding with fuel, difficulty starting, rough idling, or black smoke from the exhaust, all indicating an incorrect fuel level in the float bowl.
Is setting the float height necessary after installation?
Yes, absolutely. After installing a new valve and seat, you must check and adjust the float height according to your engine's service manual. An incorrect float height will lead to poor engine performance or flooding.
Why should I replace the valve and seat together?
The needle valve and its seat are designed as a matched set to create a perfect seal. Replacing only one component can result in an imperfect seal, leading to persistent leaks and fuel control issues. Always replace them as a pair.
