Definitely try another timing light. IMO dial backs are garbage.
See what I said..some like the dial back... but
yet MSD says DONT USE THEM... that Flaming River
is the best I own. and I have a FEW.. no battery
to hook up.. clip it on the wire(it makes a difference
which way its pointed)
I have a couple of timing lights..one Craftsman and one other one. Neither are dial backs. IMO those were made for mechanics working on Hondas and toyotas.
Thinking about a FR light. Just never needed it. But I may get one and check it against what I have.
The OP needs to get a timing light and stick with it. If you pay me to do your tune up, I do it with my timing light because I trust it, and the check it with yours. If the numbers are different then you use YOUR timing light. I don't care if your light says it has 60 total, as long as it repeats. Or you have to get a different light and check the new one.
