So I just bought my first Johnson sled and it was someone else’s project what a mess. Motor has to be pulled apart due to the guy taking out the crank seal trying to get the primary off and breaking the clutch in the process. How does the remaining part of the clutch on the shaft come off? Are parts available to rebuild this motor where would I find them? What year clutches will work with this sled? What year parts will interchange with sled? He said the eng ran before he tried to pull it apart. Body’s in pretty good shape except for a small hole in the belly pan near the left strut. Seems like most everything is there. Tracks all there. I got it for $175 how did I do??? I would love to get it back on the snow but I don't want to go broke in the process, is she worth saving or part it out? Pics when I get her in the garage.
