Answer 1

The timing should be set with the vac.adv. off the dist. and plugged.8% is the correct setting if there have been no modifications to the engine.When you hook the vacuum up after setting the timing,yes the mark will change because the vacuum will advance it if it is working correctly.

Answer 2
