Fairly certain that is the ASV (air suction valve). It has tiny reed valves in it that fail over time.

 

When converting the carb to a Weber, we pull that off, pop a quarter in it, and fasten it back up. The quarter blocks off the exhaust heat and gases, that whole ASV is a emissions devices, it helps the CATS run more cooly and not burn up. Once the quarter is in there, the we are done and call it good, also removing the rest of the piping to it.

 

You still have a factory carb tho, so wait til others tell you what to do.

Yep - you blowed up the infamous Air Suction Valve.

 

Unthread the metal pipe going to the valve and insert a quarter down into the valve body. Thread it back together and you are golden.

Anytime you can fix your car for $0.25 you don't have much to complain about!
