When I rebuilt the PTO on my 122, I put the clutch spring on backwards. It never adjusted quite right, and I could never get the fingers to stay in the groove on the PTO button. I had to adjust it down really tight and then it always wanted to run. I failed to realize this until I was working on the engine on my 107. Always pays to have pairs I guess ;-).
You might check your spring and make sure its on the proper direction. Apparently its not hard to get this confused.
