You might suspect the carburetor, but this vehicle probably has the old points and condensor igntion, so it could also be a problem with the dwell angle, or the points just have pitting or corrosion and need to be filed a little bit (but once you file them, you really need to check the dwell angle).
For this vehicle, you will need a timing light, a dwell meter, and a Chilton or Haynes guide.
Unless you know the carburetor has been tampered with, or that the float(s) have holes in them or are stuck, don't mess with it until you've set the dwell and timing. The carb is usually the last thing you need to touch!
Also, you may want to disconnect and reconnect the wires to the ignition coil and the spark plug wires. Do the plug wires one at a time so you don't get the firing order wrong, and be careful to remove them by holding the boot rather than pulling the wires directly. Do that on each end of the cable, as well to ensure they are reseated properly and any corrosion film has been broken.
