First, congratulations! I simply love the '76 and '77 models. Second, you might be onto something there. Both of our cars have low mileage, were driven infrequently yet are old. About the black smoke, it may be the engine is running too rich, or it could be due to oil burning. Could you be more specific about when the smoke occurs and is it really black or is it bluish in color? Again, congrats!
