Edelbrock 1406 Not Pulling Fuel into Carb

I'm sure i missed something, but you manually filled the bowl and got a pump shot. So if the bowl won't fill by cranking the engine and all the lines are clean, it has to be the pump, something with needle or the vent is clogged. You didn't mention why the carb was off in the first place. Was there another issue you were dealing with?
