Hi, I recently put an edelbrock carb intake and MSD cap, rotor, wires, and new spark plugs on my 68 CDV. I adjusted the air/fuel mixture screws and now my engine has a knock when idling. It goes away when you step on the gas. The car starts,drives, and runs awesome other wise. Any ideas what this could be????
