I know this is NOT an Arctic Cat site... But I started working on this sled for the kids, I got it free from my brother. I started by dumping the old gas, it hasn't run in 3 years, and cleaning the carb, a Walbro WF 7, I believe. I thought I was being careful, but when I put it back together, it starts, when I flip the choke off it then revs up really high, I hit the kill switch, and started again, same thing. If I flip the choke back on it settles down but not to idle. I thought maybe I had the idle pickup tube in upside down, I flipped that over and then it would start but not run, so I took it apart and flipped it over the way it was. I made a new gasket for between the carb and manifold, that didn't help, I also put a new vacuum line form the crank to the pump. I'm going to take the whole thing apart again tomorrow. Does anybody have any ideas?

Alot of times the crank seals will be bad on these and you'll drive yourself crazy trying to adjust the carb, but it never makes sense when these are leaking.With it running spray some carb clean or wd-40 down around the crank seals and see if the idle changes.Sometimes if there real bad it'll just kill the engine when you spray it down around there.These old kawasaki engine can be one thing after another when they get to be 20-30+ years old.

Thanks, that was going to be my next step. I haven't had a chance to take another look at it yet.

It's the crank seal. I just fired it up and was looking down around the clutch and something was bobbling around down there. I shut it off. The seal has fallen out of it's seat. I ordered a clutch puller, I should have it Tuesday.

I know... I had a lynx with a kow. It was beast to start, even after the carbs were clean and set. But I thought it might be a fun project with my kids.
