If it is running very rich, the exhaust will cause the catalytic converter to plug up, worsening fuel economy, and eventually making the car not run.

Wow. Emission tests really are not a waste and do a lot to help air quality. I remember what California was like in the 60s. From what you said it sounds like it is running too rich when it is being run on the dyno. Even though the car has a carburetor, a 1982 model has electronic engine controls. It could be a problem with the carb, it could be an oxygen sensor....and the list goes on. It is best to have it checked by someone who knows the system. If it is running so rich that it is failing the test repairing the problem will save you a lot of money on wasted fuel as well as improving air quality.
