Actually, it's just the opposite. The vacuum is setting it to 2 degrees
ATDC and goes away when the RPM increases, but 10 degress BTDC is correct
without vacuum.
I agree on the time limit for dialing it in. It took me at least a week of
fussing before I sorted it all out and got things running properly. It
could me done in less if you knew the engine, but it was unfamilar
territory for me too.
