This is DEFINITELY an ELECTRICAL ISSUE. Minor though. I have to chime in here! I noticed that the voltage on your gauge is low when the engine is faltering and then when it starts running good it goes back up to where it is supposed to be. I had a similar problem a couple months ago that led me to put in a new alternator (that I didn't end up needing!). The engine would run just like yours and I had to keep hitting the gas. I could actually drive but had to keep the choke out so it wouldn't stall (so I initially was blaming the carburetor too). BUT my problem ended up being a short in the carb fan cooler circuit. Weird I know. That short for me was burning out the "engine" fuse circuit, which also runs the voltage regulator at the alternator. Try unplugging the connector to the carb cooling fan. You don't need this thing to work (mine is unplugged now) and I read on other threads here that it is a common issue - the wire that runs to the switch that runs the carb cooling fan gets fried because it's so close to a heat source. Also check the 15A fuse called "engine" - but your fuse probably isn't burnt out since it will start running right again. The car will NOT run right and you will have low voltage when the engine fuse is burnt out. AP
