My one 1220 is giving me problems going into gear. When I push the pedal to put it into gear but pressing the pedal does not seem to do anything. It will go into gear if I kinda force it . All the linkages are there and in tact. the clutch disk seems to be pretty thick. (I compared it to the one I had rebuilt last year). Just seeing if anyone else had any Ideas. before I spend money I dont need to on a rebuild.
