New vacuum advance didn't fully fix it, but it's better than it was. I am getting a full 36 degrees of advance now, too. I ran it with and without the EGR connected to vacuum. It actually seems to run a little better/richer with the EGR disconnected.
I'll take the carb apart again, remove the power valve and make sure everything's clean under there, then I'll try the idle adjustment procedure Ben mentioned above.
