Well, the second time is the charm.
I took it all apart again and all I did was to make sure the pilot bushing was greased and I filed down some points where the Spirol pins on the drive plate had squooshed out some when I replaced them some months ago. I watched the action of the clutch as it malfunctioned yesterday and this is all I could come up with I smoothed those pins down with a file and then polished them up with a strip of emery cloth. I have no idea if this had anything to do with the problem, but I think so. There's not a lot of wiggle in the engine mounting holes but all seems to line up fine now.
A little bit of the normal waltz between the brake adjust and the clutch adjust and all is fine.
I need to put the fenders back, but it's good to have it back working. It wasn't much fun doing it over, but nice to have it working. It's still as ugly as ever.
