I had a similar problem...
I was getting vacuum advance when I wasn't supposed to...
Check microswitch operation and Vacuum solenoid (which is connected to the vacuum line that connects to distributor).
No need for a gauge, you can feel it with your finger on the end of the hose.

only from the past can we choose the correct path for the future...
Once you confirm vacuum at the distributor, check the timing as Bitsy suggested...at Idle AND high rev.
(Sounds a lot like low timing....)

I would suggest following this guide on checking correct routing of the vac pipes (without the need to remove the manifold):

Following by verifying the ignition timing is correctly set at 13 degrees btdc.
Today we checked the vacuum and timing. All was good there.
However when we started checking the fuel injectors we noticed a bad spray pattern on the first two we pulled out and checked.
Does anyone in NJ offer fuel injector cleaning? I'd be cleaning all 6 of course.
