Fuel pouring out Edelbrock - why?

Great responses thank you. I have a carb kit coming, will replace the inlet valves and seats, accel pump and floats.

Basic stuff but I'm just not used to these Edelbrocks, only ever worked on the Carter FB and AVSs, wasn't sure if there was something else I should know. The line pinch trick is a good one.

Thanks for the good info everyone.
