I have got 2 SM420 with the same problem of jumping out of 2nd gear under load. Is it something in the synchro causing this and does anybody know where in Canada I can get parts for these. All the used ones seem to have the same problem. The on I just took out works fine except 2nd gear and probably a bearing kit.
