    Mikuni dumping way too much fuel

    Hi, On my 1994 waverunner, the carb is dumping too much fuel. even with the hi low adjustments turned in, it still dumps a crazy amount of fuel in. when i try to start it u can see it. Any ideas? Thanks.

    either way, time for a rebuild. be sure tyo use ONLY genuine mikuni parts, and replace the needle and seat.

    I noticed the arm that pushes the needle and seat was up at an angle. I bent it down a little and now it seems to run better. I will get a rebuild kit though.
