So we've likely ruled out the carb, rotor and plug wires. The cap could have a hairline crack, but for now let's assume it's good. The timing could have changed that much if the distributor moved. I'd also check the dwell, and the condition of the points as well as the condition of the cam that operates them.
It is unlikely that the fuel filter is tank mounted. It is typically an inline filter found on the supply line for the carburetor. No telling what the previous owner has done though.
Vacuum may cause this, I am unsure if the advance on your distributor is mechanical or vacuum operated, if it is vacuum operated then vacuum problems might cause this.
