Q: The car won't run for longer than 30 sec.

So I bought this starlet in the hopes of restoring it, as my first car. I'm 17 and have done everything myself. With a mediocre knowledge of how to do it. Anyway, it ran ROUGH and died VERY quickly when I first Started the project. After a couple of shots of carb cleaner, it ran, but only seemed to fire on 3 cylinders when below 1500 rpms. So I replaced all the plugs and plug wires. It now starts right up and purrs like a kitten, but it idles at about 2000 rpms at a full choke, witch is necessary to keep it running at all. After a few moments it will act like I need to ease off the choke, but as soon as I do, it begins to act starved of something, and immediately dies. But if the choke is engaged again the process will repeat. I'm simply stuck and desperately need a pros help. WHAT IS WRONG?!?!?

My car has 132500 miles.
My car has a manual transmission.
