Black smoke is usually an indication of unburnt fuel. I would check all of your ignition components. Pull at your spark plugs after you run it for a minute and see which if not all is wet and black with fuel. That would be were i would start. And it should help lead yoy to the culprit wether it be a bad could pack or ignition module, plugs or what have you.
