Hi all. Just back from a great week of sledding in northern Mich. @ the winter Jamboree. We have a pair of Jags. Says '91 on the side, cousin says that means they are '92 ? Need belts, wear bars, probably lugs, do they have a little piece of carbide in them ?, a service manual. One runs great, the other to rich I think. Where do you get good deals on parts ?
