Make sure your catalytic converter is plenty hot when you get it checked. 15 minutes of highway driving is good. You need to be running gas that has had the max amount of ethanol and/or MTBE added- not premium. I agree that it is running too rich. Since you have a carb this is a pretty easy thing to fix with a meter and a screwdriver- 1/2 hour shop time and it will increase your mileage greatly as well. Basically, your car needs a carb and timing adjustment (1 hour shop time) before a new cc. Even if that doesn't fix the problem (it will) it will pay for itself in increased gas mileage. Oh, and air up your tires too.
