my vacuum advance was leaking I just removed it adjusted the initial to 24 total 34 runs awesome .probably burning more gas though
Excellent analogy and demonstration, thank you!
A swing weighted advance ,Advances "in the direction of rotation" & vacuum advance cuts Against rotation .
note aftermarket cams with big overlap (pulse ) inside the intake manifold even though the gauge reads steady. and bigger than stock intake runners amplify this Non seen effect,.
Thanks. The videos on advance curves are great. Part 1 and 2 answered a lot of questions.
I am 69 years old and have never been a car guy. I can now understand how it works and will research how to adjust the curve based on the dozens of variables presented by my car and engine.
As a member of the human community, I must apologize for some of the comments made here.
how do i TUNE the damn thing!?
wtf?

Don't take it the wrong way dude… that was funny! Anyways, should that vacuum line have vacuum to it constantly so it has full vacuum advance until the throttle is opened?
What are you talking about?
