Not a difficult rebuild, order a rebuild kit and follow the directions. One thing that you want to pay close attention to is the wells in the bottom of the body, they can become loose and leak. With that said if you can get them off and clean them up and get a good 2 part epoxy for automotive use and re-glue them in place that would be a good thing. If you do this make sure and let the body sit for a couple of days to be sure the epoxy has sufficient time to set up. Clean everything else and blow all of the passages out and reassemble. Pay close attention to what comes in the kit, I can't recall but I think I had to order brass floats separately. Here is a link that might be helpful. http://www.moparnuts.com/images/stuff/Tquad2.pdfHere is another link that might be helpful. http://www.carbkitsource.com/carbs/tech/Carter/TQ-index.htmlAnd of course you can check with Scott at http://www.harmsauto.com/ he is on this board.

Your '71 ThermoQuad is a one year only design and does not use the x-style o-rings used on the '72-up carbs and the bowl does not have the epoxied wells either!
So my advise would be: clean the bowl well inside/out,
be sure the accelerator pump nozzles are clean,
set the float level to 29/32" with the top bowl gasket on the top casting and the top casting inverted,
be sure to return the accelerator pump check valve under the accelerator pump nozzle cluster with the pointed end down,
straighten any bend to the metering rods,
remove the old needle seat gasket when you remove the seat,
use a light oil on the threads of all screws when you assemble the carb,
drive the old accelerator pump assembly/well cover out of the top casting with a punch; strike the exposed end of the accelerator pump stem after you remove the pump arm and 'S' link, driving the pump straight through the top casting. Do not attempt to 'chisle' the pump well cover off.
And make sure all old gaskets 'match' the new ones, David.
