Got the chance to check it out. It worked. I did what you said, pushed the plunger, which was still stuck, back, flush to the housing, then reattached the solenoid without the wires connected. I had disconnected the wires and wrapped them up, then pushed them out of the way. It started up, and I mowed for an hour. Then stopped, waited an hour or so, then started again. It started right up again and mowed for an hour more. Not sure if it's a permanent solution, but it's working. Thanks!!! I really appreciate it!!!
Thanks so much for your help, and everyone's help, and your patience with someone who doesn't know much. I know that can be frustrating.
All the best. Thanks again.
