Update - all is fixed. Turns out the fan belt was improperly/not shimmed
(I learned something new) and it was too tight - thank you previous owner
- no shims at all between the pulleys. It spread the inner pulley, making
it rub against the generator.

Went down to my local Bug shop (yea Archway in StLouis) and picked up a
new pulley set, shims and a woodruff key (had the wrong one of those
too). So, $15 later and new knowledge on how to shim a pulley - my SB is
better than ever.

Oh, I have a pict30 carb too - wrong one for my engine.
