Just looking at this link and it looks like it was completely retarded:

I'm assuming with today's octane fuel, this should be closer to 10-advanced?

Also, when I was advancing the dizzy it didn't seem to rev up and then start coming back down again. Some of the stuff that I was reading said that once you go past the high-point, it should start to come back down and you bring it back to the high point again. Without a timing light (for now) is this correct?
