Troubleshooting & FAQ
How do I know if this carburetor kit fits my engine?
This kit is for specific OMC/Johnson/Evinrude 22–40 HP 2-stroke models from the 1950s–1970s. The best way to confirm is to match your original carburetor's OEM part number to 439075, 439074, or one of the listed cross-references.
My engine bogs down, stalls, or floods. Can this kit fix it?
Yes, these symptoms are often caused by a faulty float, a worn needle and seat, or failed gaskets, all of which are included in this repair kit. Rebuilding the carburetor with these new parts can restore proper fuel delivery.
Is installation difficult for a DIYer?
Installation requires basic mechanical knowledge and hand tools. You will need to remove, disassemble, clean, rebuild, and reinstall the carburetor. If you are not comfortable with this process, professional installation is recommended for safety and best results.
