Edelbrock Fuel Pump and Carburetor

let me get this straight. Engine was rebuilt 6mos ago. Carb is brand new. correct?
What kind of rebuild are you talking about? Stock rebuild? or bigger cam, etc? Please be as specific as possible.
Was engine first started and run-in on this new Edelbrock carb or a different carb?
When you said it "wouldn't crank", do you really mean the starter would turn the engine over (called "cranking"), but engine would not start?
