Having just done this yesterday on my 76, I can tell you exactly what it
should be. Vacuum connected, 800-900 rpm, and 2 degrees ATDC. I set my
at 1000 rpm, vacuum connected, and 0 degrees because that's what felt
right and ran well. In fact, if I back off to 800 rpm, it would
probably be at 2 degrees ATDC.
