I did some reading here in past posts about the 93, 94 wildcats. There were mixed reviews. There can be stator problems and there is the possibility of efi concerns in general. (sensors and elect. connections) Mostly I read about concerns with the battery needing to always be in top condition. Low or no battery power = no start.
I bought a 94 at the end of last season. I have not had much time to try it out yet but I am liking the 2 pull starts, and seems to want to run strong.
I really feel that no matter what sled you have, if it was bought used and the prior owner(s) did not take care of it, then it could be a headache.
I say go for it Wildcats rock.
