ok it runs but poorly??

unfortionatly no one even in the county has a dodge. Part of the reason I switched from Chevy to Dodge. I have not seen one around. I have changed almost everything to try and repair this. 3 intakes, the Holley, a stock 4bbl, and the stock 2bbl. 3 carbs, an 850 eldebrock, a 600 Eldebrock and the stock 2 bbl. removed the carb spacer. played with the timing until blue in the face. checked firing order half a million times. 2 sets of plugs new wires, checked for vacumme leaks. Can a stock mechanical pump, go bad and put out to much fuel? the stock 2bbl I had pulled off last month, and out in a bag, was pouring fuel out of the vent tube withen seconds. I installed a line restictor in the fuel line, but that did not help. gonna keep at it untill I find something. thanks all
