Sorry, for sounding like a noob but im learning. I have a 1989 5.0 Notchback. The person that sold me the car told me that he had retarded the timing on the car for whatever reason. He said I'd need to advance it again. I know it needs to be set at 10*. My Q is, How do i advance it? Is there a small screw or something I need to adjust? If there is, where is it located? Thanks :SNSign:
