Thanks, I'll check that as well. I did talk to one of my techs here at work who has some snow mobile experience. He explained the basics of the clutch system to me. What I'm still confused about is the plastic covered dome on the driver's side, in front of the rear differential. There is an articulated metal tab in front of this that is connected to a cable running up to the carb. It was frozen up, with the tab touching the nose of this dome. I freed it but the cable id loose on the carb side. I don't see any way for this to operate. Is this "dome" a magnetic actuator of some sort? If so, does it control the halves of the clutch? I'm not trying to jump ahead of the basic diagnostic procedure, just understand how this is supposed to work. I'll keep you all informed. Thanks for the help.
