Piggy back question to my timing a 360

crackedback said
DO NOT readjust the timing with the advance hooked up.

You have your total number without advance hooked up? You need to do that first.

Initial, mechanical, curve, vac advance in that order.

OK now I feel dumb. I thought mechanical was with the advanced hooked up.

OK initial is with the advanced unhooked, carb plugged at idle.

What is mechanical?

What is curve?

Vacuum advance is obviously with it hooked up and nothing more should be done.
