have you ever seen this before

I fired this goat up. after turning the dist. cap around and getting the firing order correct it ran fine except for the carb. When I rap on it , it wants to lay down on me. Has a dead spot in it. also when I shut it off it wants to keep running a little and blows a little fuel out the top of the carb. I think it needs some fine tuning and I don't know **** about a Holley. Inside of the carb has a lot of fuel on it.
