Carter BBD Help

Hey everyone I'm looking for some advice. I have a 69 Valiant that has been sitting for about a year and I've been taking my summer break from school to get it running again. Long story slightly shorter I've replaced the old points dist. while switching over to a HEI setup. I have also ditched my single barrel 1920 for a Carter BBD and the super six manifolds. Here is the problem, when I got it put together it will start but immediately dies as soon as you touch the gas causing the choke to move from the initial position. I consider myself pretty handy with a wrench but carburetors give me a headache. I rebuilt the carb making sure the float was set correctly but I am not sure about making other adjustments. If anyone could point me in the right direction as to what may be causing this issue and how to make the proper adjustments I would be grateful.
