Just one last question. If the points were bad after 20 years, why did the car start right up? And it ran great, beautiful smooth sound, sounded better than my hinda accord! Ran for more than 1 hour straight on each of the 3 starts. Would the point actual get worse upon running.

Can I just use a test light probe bought at autozone?
