If the car is running rich, chances are the carb needs adjusted. Aside from a rebuild, you can adjust it for better performance. There are two idle air screws at the base of the carb. With the ignition off, turn both clockwise until you feel them seat. Do not over tighten as they are soft brass and will distort. Then, turn both back out 1 1/2 turns each. Start the car and slowly turn one screw back in until you hear the engine begin to stumble. Then turn the screw back out until the engine again smooths out. Do the same for the other screw. This will get you close to the factory settings and it should give you better performance.
