Default carb autolite 2100
Hi.
When I take the top of the carb off. It is a little low on fuel. The weird thing is when it asks for fuel it sprays out of the needle valve. This is all new. Could the be becuase my fuel pump is bad?

If the floats are set right it should be fine. When you remove the float, which is displacing volume in the bowl, the fuel level will drop. How does it run?

What's the fuel pressure at idle? It should only be around 6lbs or so.

didnt have anything to check it. If the fuel going in is a 3/8" copper line how do I hook up an adapter to check?

Buy fittings.

Is it only rich when you drive, or does it flood at idle and low rpm?
