Should have a 3/8 line, but it sounds to me like your carb needs adjusted. Start with adjusting the 2 screws in all te way and backed out by 1/4 turn.

fuel line size won't cause it to black smoke. You have carb problems.
Too small of a fuel line will hurt power at WOT Too large of a fuel ine won't hurt anything. |

What fuel pressure is the supply to the carb at? These edelbrocks are picky about to hi a supply pressure. It will run rich all day long if supply pressure is to hi.
