I just bought a 86 200sx and its definitely running too rich, what are the factory settings on the carb? Also it has an NGK DR8ES-L in it. Im not sure if this is the proper plug for it anyone know? I lubed the throttle cable last nite and figured i fixed my problem, after you accelerate and let off the gas it wont idle down like it should to make a smooth shift, any ideas on that one??
