Fuel pouring out Edelbrock - why?

As Murray said. Is there a fuel filter? Blocked? Problem could be dirt/debris under the needle & seat.
Also, after a lot of miles, the n/seats become worn & will leak. That carb looks like it has seen better days....
Carefully remove carb top [ no gaskets needed if you are careful ].
Remove & check floats for debris in the n/s area. Using warm water, gently push the floats under; they should NOT take in water. Make sure the floats are straight, not hitting the side of the carb body. Set float level to 7/16". With floats back in position, invert carb top & suck on the fuel inlet. If you can suck air, you still have a leak...
