The present day gasoline has nothing to do with burning points. They don't get together. It is very possible that the battery is in backwards. Those old Fords have positive ground. The spark advance shouldn't affect your points. The advance is used primarily for economy. A look at how this works and it helps if you are from the vacuum wiper era. You set the time on a motor with vacuum advance with the hose disconnected. When you hjook the hose back up the timing will advance. When you get on the road and get up to cruising speed, the manifold vacuum will increase and advance the timing. When you step down or go up a hill, the timing will retard to the preset timing so that you don't blow head gaskets or burn pistons. The same holds truefor the manualadvance on the old A's. No experience with the electronic systems on them. We use a MSD (multiple spark discharge box on out super late model race car with success. Sure makes it crabk quicker with no cutting outat high RPM. I've never gotten hold of one of the plug wires, but, my son has. He said something, among other things, about it"knocking the sap out of him"
