Barring a mechanical issue with the distributor (vacuum canister not connected to mechanism), you might just need stronger springs or lighter weights (like Mickey suggested) to help hold back the advance till it is needed.
Relatively low engine speeds/load will require less advanced timing for the same fuel charge. Now, obviously there are diminishing returns for adding advance timing, but your car will perform better if you swap the springs for stronger ones.
But thoroughly check the distributor for defects to make sure nothing else is interfering.
So I agree that I need stronger springs. I guess my bigger issue is that I'm not getting enough advance in the fist place I should see at least 32, and not 28 right? What would cause that?
