Car putts

[1974 dart]

I have a 318 dart that when I was driving home started to putt. Yesterday it made some putt sounds maybe once when I would get on it. 3 days ago it ran perfect! The only thing I can think of would be clogged fuel filter but what do you guys think??

Plug wires or plugs?

Has brand new plugs and I checked all the wires they seemed good.

Distributor cap and/or rotor?

 

[1975Scamp]

Plug wire not on tight?

Does it still have the heat riser? Maybe stuck closed?
