This is my buddy's ski. He just got it running the first time this year. We hooked up the garden hose, fired it up, turned on the water... I turned the idle up a bit to keep it running... a couple minutes later it sounded like it was about to die, so i told him to goose it. He did and it reved up and wouldn't slow back down when he let off. He pulled the dead man key, still running. He pulled the plug wires, STILL RUNNING!! So i shut the choke butterfly and it slowly came to a hault. WTF??
