Danny, I can add little to the fine recommendations you have recieved from the other posts, but have a couple comments. "spits and sputters while driving around" sounds like an ignition problem to me, not a carb problem. New points, wires etc. was a good idea, but you still need to verify you have the "bluish-white" spark.
Don't forget about that elbow strainer that screws into the carb, might be clogged. You may be able to install a Ford-style gas shut-off which has a screen inside the gas tank to keep junk from getting into your gas bowl. The sloshing of your gas tank helps keep that screen clear. I know the Ford gas shut-off is a perfect fit in my TO-20 tank, not sure about your TE-20, it would probably work fine. Ultimately, you will likely need to spend some time/money cleaning out your tank if the rust is really that bad in there. In addition to the ideas below, I've heard of guys throwing a piece of chain in the tank, strapping it to a rear wheel and driving around for a while, also heard guys use gravel. Call around a few places, might find a place that will do the chemical cleaning deal... one warning on that, we use acid to clean rusty steel jacketed vessels where I work... .sometimes the acid does "too good a job", and you end up with leaks.
Several guys have installed car in-line plastic gas filters with rubber fuel hose. If you do that, get the biggest filter you can find, most of those filters are intended for pumped fuel, not your gravity flow fuel system. I'm not a huge proponent of rubber fuel lines, imagine the fire potential if a rubber gas line were to let loose above your hot engine.George
