If you add initial, be sure to recheck the total timing (w/o vacuum advance, vacuum line plugged). Keep the total under 36 degrees for non fast burn chamber heads, 30-32 degrees for fast burn.
If you have no change when the vacuum advance is disconnected, you're either using ported vacuum or the vacuum advance unit is bad or the advance plate is hanging up. Try hooking it up to a vacuum port that has vacuum at idle (manifold vacuum).
