Ran good yesterday.Today rich real bad.I've got gas puddling on top of where the acc pump rod goes.I put a new fuel filter on between the fuel pump and the carb.I can run the idle mixture screws both ways with no difference in idle.This is on a 71Z/28 auto.

Either send Edelbrock tech support an e-mail or call them tomorrow. They're good people and should have the right answers for you.

Thanks,I'll do that

Sounds like a float sticking.  Perhaps some crud in the needle and seat.

I took the Carb back to Auto Zone and they gave me another one.I do have another ?do I need a return line?I don't see where one would go.

If this is an '82, it should definitely have a return line. The '82s were injected(sorta!), and required a return line. Chances are, it is at the rear of the engine, where the fuel line comes over the top of the bellhousing.
Also, if you are using a regular carb on a fuel injected set-up, your electric fuel pump may well be putting out too much pressure for a carbs needle & seat.


Oh !!...I just saw the part at the bottom of the post about this being Mama's Z28...never mind...
