5000 Penny Special 2: Rough Rider Mower Won't Start Troubleshooting Part 1... Good News and Bad News

Craftsman riding lawnmower won’t crank and won’t start. Can a Master Automotive Technician diagnose a lawnmower with only knowledge and simple tools?
Unexpected discovery changes my plan for this project.

Why don't you look for a electrical diagram online?

I’ve been able to find engine service manuals in the past, but I’ve never had much luck finding the diagrams for the mower itself so I didn’t even bother.
I thought I might get lucky if the engine warmed up a little bit and sucked some more through the carburetor, but there was no saving that carburetor.
Thanks.
