The two areas I would concentrate on would be the fuel enrichment circuit of the fuel system and the vacuum advance for the distributer. Make sure the frequency valve is buzzing and check all of the vacuum hoses to the distributer. It is easy to knock one loose but very hard to see into that area. A hose could also be incorrectly connected so use the diagrahm to follow the hoses making sure that they aren't brittle and or cracked. I don't think it is voltage related but it could be made worse by a breakdown in the secondary ignition wiring.
