1 BBl Carb. Leaking

I haven't touched anything on it yet. Can't get to it right now, but I am trying to get ideas on typical problems. I have been driving it, but I took a long trip and it started to sputter a little. Popped the hood and noticed the fuel leaking. Could not determine exactly where it was coming from. I know it's common for the Carb to loosen around the Base Gasket, but I don't think it would leak the amount of fuel I saw. Not sure?
