Quadrajet issues

[Cyanide93]

My carb had developed a bad leak out of the accelerator pump, I cleaned and rebuilt the whole thing, threw in new plugs and a coil and it fired right up. It seems to run strong but smokes like a son of a gun, it's always had blue smoke but now is a mixture of black. I've tried adjusting the idle mixture screws with no change. I bottomed both sides out which should of killed the motor? Which it didnt. Any pointers for tuning this thing?
