    new problem 99 SLTX

    I have only put a few hours on the jetski since I rebuilt the carbs and changed out the fuel lines. Today while riding everything was going well, although while doing some S's something gave out and the power dropped pretty good. I couldn't get it over 4000 rpms...barely able to plane. I thought it was low gas so I filled it up...nothing changed. Oils is good too. Out of the water she revs up, but under a load 3500-3800 although idles normal.

    Thge odd part is I can hear something pumpping or squirting...I took the seat off and I can see it's carb 1 something causing a small spark all the way down in the carb. Smoke is also coming back up the carb...like its blocked or something? All three cylinders are equally warm...I'm wonding if this is a reed valve issue? Maybe there is no compression? I don't have a guage yet.

    Any ideas? Also, the exhaust smoke is more visible then it was?

    Any help is much appreciated.

    I planned a tear down this winter anyway, so don't mind bad news if that's what it is.

    Sounds like a reed valve failure, but there is something else wrong.

    Check cylinder compression.
