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

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

Yeah...what Ken said!!
