Sounds like a vacuum leak. Is the new advance defective?
Plug the port feeding the vacuum advance. Idle different? Acceleration
different?
Advance the timing a few degrees. Running better? If so take a close look at
your
new vacuum advance and the line running to it.
If no change, still sounds like a vacuum leak. Spray WD-40 around the intake
gaskets to see if the idle changes. If so, that's were the leak is. Be careful
about hitting the exhaust manifold. Have fire extinguisher ready, yada, yadda.
