Troubleshooting & FAQ

How do I confirm this kit fits my specific engine model? This kit is designed for most Johnson/Evinrude V6 150-300HP engines from 1986-2001 and V4 90/115HP Loopers from 1995-2006. The best way to confirm is by matching your engine's model and year to our "Compatible Engine Models" table and cross-referencing the OEM part number, which should be 438996.

What are the signs that my carburetor needs rebuilding? Common symptoms include difficulty starting, rough idling or stalling, poor acceleration, hesitation, or black smoke from the exhaust. These issues are often caused by degraded gaskets, clogged jets, or a faulty needle and seat, all of which are replaced with this kit.

Are any special tools required for this rebuild? Standard hand tools like screwdrivers, wrenches, and pliers are generally sufficient. A quality carburetor cleaning spray is essential. A pair of forceps can be very helpful for handling small components like the float pin and needle during reassembly.
