You were right about the inset terminal nut - used needle nose pliers to get it out. This morning got the points in and set, and with starter fluid got a few chugs out of it. It's alive! However, the starter engage gear kicks out on the first chug, so I can't keep cranking it to get it started. The starter spins for a moment and as it slows down a little clunk happens, which I think is the starter gear sliding back into place. I have another starter, it should fit but it's not a foot pedal starter.
