Kraig M: Haven't had time to work on the 71 since I posted last. I had the same manual you posted when I put it together. I'm starting to wonder if I may have pushed the bearing back on the crank when I installed the clutch, and now the whole assembly is too far back and there is too much distance between the wear button and the thrust button. I have a 105 also, and was looking at it for guidance. The bracket that the wear button pivots on is much closer to the clutch on the 105 than on the 71. I noticed in the manual it refers to a "snap ring" that I'm assuming acts as a stop for the bearing inside the clutch. I don't recall seeing a "snap ring" inside my clutch, I just figured the bearing bottomed out when it hit the furthest point inside the clutch. Maybe that's my problem. Appreciate the help, I'll post again once I get it apart.
