vacuum advance

Not too shy to talk

How would one test the vacuum advance on a 1937 Packard Six?

Home away from home

Well, without a vacuum pump, just suck on the thing and put your tongue over the opening and see if it holds. You can also watch the arm move. It it does not hold and/or the arm does not move it is defective.
