Regarding the stop solenoid replacement, I can vouch for alignment of the solenoid in the slotted mounting holes being critical. I am a very good person to learn from because I usually make all the mistakes. When I first mounted my shiny, new, Chinese solenoid, I just slapped it on without regard for how the bolts ended up in the holes. As a result, I had it in a bind and, sure enough, it didn't reset after shutting off. However, with a little adjustment I gleaned from bordercollie's documentation of a comment from her dealer about not getting it in a bind, it now works like a charm. I had to re-read bordercollie's posts to pick it up. I knew in the back of my mind I read something somewhere about alignment of it. Duh!
