In listening to engine turning over, it sounds like the timing is off. Sounds like it's advanced too much. Could be a weak battery but I recommend that you get #1 cylinder on TDC on compression stroke, make sure the BB on the flywheel is centered on the pointer in the timing hole, then static time the distributor to where the points "just" open at that point. You can use a light or disconnect the distributor wire and an Ohm meter.

Then make sure all bolts at the carb and intake manifold are good and tight. Not gorilla tight, wrist tight.

Good luck
