Don't wanna get into a pissing match but u have more vacuum at idle and less at wide open throttle. The reason cars come with vacuum canisters. To hold on to some vacuum to operate accessories during hard acceleration. Again my answer is still (google it)

You are not understanding. I'll put like this at the intake there is no vacuum at WOT but there is vacuum at the throttle plate "air going in" and thats where you get vacuum for the advance part. I wish you lived close I would show you. Also if you are timing cars and putting direct vacuum to the distributor you are doing it wrong.

Not trying to be a d!@k about it but how long have you worked on cars? I've been working on them for 12 years. I know allot about older one but it gets confusing when dealing with the computer crap.

Please put a vacuum gauge on a vacuum port on your intake at idle. Should be about 13-15 inches of vacuum. No offense.

I'm sorry forgot to say at WOT there is no vacuum but there is vacuum at the throttle plate.

Thats a whole another issue with psi going to the distributor instead of vacuum.

ok have fun guys!

There is a difference between ported vacuum and manifolds vacuum. And I never said that the advance has anything to do with base other than the fact that on a vacuum advance car you typically time out for total timing instead of base. So you rev it to 3k and hold it so that the mechanical advance is all the way out and your vacuum advance is a well.

that dist is mechanical advance !!!!!
you really can't time it correctly without a timing gun / light
set it to about 14deg advance when you do get a light on it ,they run good right about there ...
get one with a dail on the back ,set the dail on 14
put a mark on your harmonic balancer where 0 is with some white paint ,so that you can see it then while its running move the distributor untill the gun light flashes on the mark lined up with the timing pointer on the engine ....
