I scored this Horse off the side of the road for free the other day. I got it running well but I'm having problem with the drive. The belts are slipping unless I hold down on the engagement lever. I havent had a chance to look at it too closely but I did notice there seems to be slop in the main drive pulley at the trans. Looking at the IPL, there is only a snap ring that holds this on the shaft so it seems one would expect to see some movement there but how much is too much? I'm thinking this might my problem along with stretched belts. Anyway, here she is. It is a January of 1977 model with 6hp Tecumseh.
