Did you play with the base timing with the vacuum disconnected? If it's idling too fast & the idle stop is essentially closed, then probably too much advance at idle, or still have a (intake/vacuum) leak - OR (most likely) the cam timing is off, IMO.....
I just played with the ignition timing with the vacuum still connected. I'll have to fiddle with it some more and probably make minor tweaks to the cam timing. I wish I could find a shop that I could just pay to do this for me but everyone I called said it's too old and/or too mysterious and they don't want to mess with it. I would gladly take it up to Columbus to MWB but they can't get me in until sometime in August and I would really like to drive this stupid thing.
