Update - the two light (silver) springs from MSD seem to have done the trick. The advance now comes back fairly quickly to zero advance when you release the throttle. I am still at 16 degrees base and 36 degrees advance, all in by 3,000-3,100 RPM (not easy to get it exact doing it yourself and trying to modulate the throttle linkage, watch the timing, and watch the tach at once). I'll confirm with a friend soon, but seems to be good.

I wouldn't mind the advance coming in a little earlier, but I am worried that if I go back to one of the super light Mr. Gasket springs and one of the silver MSD springs that I will quickly loose some of the tension in those springs and run into the same problem of my advance not retarding when the RPMs drop. I'll probably leave it for now as it seems to run well.
