Car would not restart

[Will N]

Could be any number of things. It might be your ignition switch is on its way out, and it wasn't making good contact when it wouldn't start, but the next day when you turned it on it made good contact. It might be the wire connecting the upper and lower plate in the distributor. Could be the insulation is cracked. When you moved the spark advance lever to restart it the day it wouldn't start, it shorted out. But the next day if you moved the lever it might have moved the wire so the short was removed.
