I think he's talking about some of the Holleys have a check valve on top of the front fuel bowl. If I remember the valve is actuated by a lever that is in contact with the driver's side linkage. It is slightly open when you're at idle and closes when you go off idle. I don't know exactly what it's supposed to do. I had a carb rebuilt by a local speed shop and they essentially eliminated it and plugged the hole.
