Your links are scrambled, but I managed to view the photos.
Yours actually runs like that???
The carb float bowl vents are plugged which can starve the engine for fuel and I don't see a gas tank vent.
If the gas tank isn't vented, then it too can form a vacuum and starve the engine for fuel.
The gas tank vent was the charcoal canister and it's flow is needed by the PCV valve for the PCV to operate properly. The PCV controls engine sludge.
You could get a PCV from a 75 which didn't use an active suction canister to get the proper crankcase ventilation. They had the 3 hole canisters that vented into the air filter snout.
Your distributor also looks like it may be using manifold vacuum instead of the nipple on the valve cover side which is a ported nipple.
