    WaveRaider 700 WOT

    This has been sitting almost 1 year. Worked good when parked (outside, but under tarp - warm & dry). Coaxed it into starting, but it immediately went to full-throttle. After several attempts, I finally got it to start with high-rev, but when I pulled the throttle, it went full again and stays there.

    The butterflys are moving at will when pulling the throttle lever - not sticking at all, and closing fully. I'm not much of a 2-stoke guy, and carburators are still a bit of black magic for me (especially duals). So, I'm looking for good places to start looking.

    Could there be a stuck spring in a jetting-port? Some valve not closing? Air leak somewhere? Any help would be great!

    Most likely an air leak. Did the engine kill when you hit the stop button?

    Yes - thank goodness. I was not looking forward to yanking spark cables!

    How do I isolate the air leak? I guess it could be a cracked casket or something. Would it be isolated to the carb / manifold. Or could it be coming from the crankcase (since there are no valves).

    Normally the engine will not stop running when you hit the stop button if it's an airleak.

    Then I'm going to verify it stopped with the button and not by pulling the kill cable. Or are they one-and-the-same?

    Normally an air leak the motor will not stop with either, you can even pull the spark plug caps and it won't stop. Most people pull the throttle wide open for it to stop.

    Does the kill-switch work the same as the stop-button. I can't remember if I was pushing the button to stop it, or pulling the cable.

    This thread is a little old but ill fill in. The kill switch is supposed to stop spark but if you have an air leak and the ski runs lean the spark isn't going to matter. The plugs get so hot it starts running like a diesel essentially turning your spark plugs into glow plugs. Only way to stop the motor from running is to remove fuel or air.

    Easiest way to kill would be to pull choke and pull throttle wide open.
