Timing light

I have an OLD Dixco tune up kit......the kind that came n the yellow plastic box back in the late 70s. Timing light, vacuum gauge, compression gauge, dwell meter and a remote starter button. That timing light in that kit is probably the most accurate light I've ever used. I checked it on the old Sun tune up machine we used when I was in auto shop in high school. It was dead on. My shop teacher said that was because it did not have the dial back advance feature and that the type lights that do not have that are much more accurate. It's always worked for me.

Just passin that along FWIW.
