Ren,
The herky jerky motion I witnessed was nothing more than your carb not getting the gas it needed. I'm no certified mechanic, but that much is true. I've taken engines down to the block and rebuilt them before. I don't have that kind of ambition anymore. But I think I can assure you of that in regards to your fuel problem.
I am a huge believer in "don't fix what ain't broken". Get your alternator tested off the car before you go messing with everything else (other than the fuel pump).
