Best Mechanical Fuel Pump

Why not just pop in a inexpensive Air-Tex pump from Kragen,Autozone,ect ?
They are actually pretty decent pumps. If it isnt the problem, at least your not out a bunch of money. You can pop it in, in a matter of minutes. If thats not the problem you can check it off the list.

Im leaning towards carb issues, like others have said.
