I would check the mechanical advance AND the vacuum advance. It is pretty simple to do with a timing light. It sounds like one, the other, or both are not coming on like they should. Before using the light a visual inspection of all the vacuum hoses for correct routing and damage should be done. I have seen on more than a few cars the mechanical advance was stuck. You have to dissasemble it and clean and lubricate it. A vacuum leak from an old, cracked hose will cause the vacuum advance to malfunction. Old, hard, leaking injector seals can also give these symptoms. Backfiring during deceleration can be caused by the decel valves not opening. They are the little spring-loaded things on the throttle plates. Check to see if they are stuck.
