Motor dies when gas pedal pressed

OK, this is a 318 2bbl 1974 Duster that I just bought. It is hard to start and wants to stumble and stall right off idle. I can't even touch the accelerator until it is well warmed up. I have to use a spray of starter fluid to start it. I temporarily wiredd the choke open to be able to run it. The previous owner put a brand new carb (2bbl) on it. Once it warms up, if I ease it through the flat spot when running in neutral, the engine will finaly rev up fine, but it is real difficult to get it to 2,000 where it will take any throttle to speak of. It's almsot like there is no accelerator pump in this carburetor. I'm starting to think there is dirt in the carb, what do you guys think? Fuel pump? Blocked fuel line?

Just off the top I would check for accelerator pump shot in case they are plugged up, then take that carb off and do a disassemble and clean on it.
Just so you know, a crappy ignition tune can act about the same way, but the carb would be a good start after a quick ignition system checkover and timing setting check.

Putting your hand over the carb about 50% of the opening and a quick tip in of the throttle can tell you if it's a lack of fuel causing it, because it will make that flat spot go away by causing more vacuum with your hand which makes the carb supply more fuel. (quick, easy and cheap diagnostics):D
