Manifold Vacuum Advance what am I not getting?

I don't mind responding and helping folks, but when they ask the same questions over and over on several different threads, it gets confusing and it's just mind boggling. Keep it confined to one thread and it'll be easier to find the information and easier for people who are trying to help YOU keep up with the subject. I've done my best to help you on other threads you've posted, but it seems like when "you can't get it", you just post another thread. I try to help lots of folks on here and I, nor anyone else is getting paid squat, so when people make it more difficult, I just move on.
