I read that you should be able to operate the vacuum advance with the amount of vacuum you can generate with your mouth?
Mine's not moving. I can move the arm with my fingers...
Do I need to use a vacuum pump?

Yes you can. You can also use your hold the vac and see if it leaks too.
If it doesn't move when you apply vac, you probably need a new vac adv, I've priced these at about $15 from a local parts house.
You'll probably want to remove yours and get an exact match as they can have different arms that connect to the plate.
As a side note, they are adjustable with I think a 3/32 allen wrench stuck inside the vac hole.

This feels weird trying to describe but it's not that easy to suck down the vacuum in order to get the vacuum advance to move a lot. Imagine the thickest chocolate shake you ever had and that's about 10" of vacuum achieved.
