running rich ... 700 1990

Have you removed throttle body and cleaned all venturis? A source of unmetered air on a car of this age can be the bushings on the throttle plate butterfly(same seals as valves)

Have you checked the Fuel pressure regulator for leaks?(remove vac hose is there gas present?)
