Replace your stock pump, and change your oil, and your problem will be solved. The black exhaust stains are from condensation of moisture. Its perfectly normal to see this on startup, and it will burn off after warmup if you drive for a while. These old cars need to be run good and hot for awhile to get all that moisture that has condensed burned off. Use the choke for as short a period as possible, and that will help also.
