I have rebuilt a couple of the carter bbd carbs now and you can buy a rebuild kit from your local parts store for 20 bucks or less. then get then pick up the kit from gunk that comes in a paint can. the carb when fully disassembled fits into the can with a little wiggle room. they are quite a simple carb. basically follow the instructions and its a sinch. the measuring tools come in the box as well as a few extra parts you can hang onto. Now with that said do some searches online about the motorcraft 2100 or 2150 carb swap. this is what i did with good results and for cheap. I think i spent 60 buck all together with a trip to the scrapyard and the parts store for a rebuild kit. now that doesnt mean you dont want to bebuild your carb now and see if it is an improvement over what you are experiencing now. This way if it still sucks you can go with the motorcraft swap and you have some rebuilding experience. Also look for the "nutter bypass" as well. no matter which carb you have this is a vast improvement over stock. It is basically to remove all the emmission components, vacuum line mess, and bracketry under the hood. depending on your emmission laws.
