Removed by poster.
I also have the factory hub removal tool.
Took gas tank out today and will go to a motorcycle shop and see if I can have the threads where the stopcock screws in removed and new threads welded in so I can attach a different shutoff for the fuel. The original just leaks and leaks and leaks even after a rebuild. Later when the weather cools off, I'll be grinding off some of the rust areas. Slow progress, but progress.
Was it leaking from where the valve turns? It's a balance between tightening the screws enough to stop the leaks and loose enough to still be able to turn the knob.
Yes. I can't find the happy middle where I can turn the valve on without leaks and where it won't leak because the valve won't turn.
in terms of rust the most important area is the perpendicular to the rockers "beam" that the motor/front suspension subframe attaches to - if that is not in good shape you should not drive it.
