timing lights ,any prefrences and why????

I have an old Actron with the battery clamps. I like the inductive pickup types because they can be handy for checking spark. I have some k&l vacuum guages that do the job. I just periodically check them all on the same source to make sure they are all reading the same.

Hey dejavoodo41,

Neat Vacuum Gauge calibration idea... checking each Gauge on the same carb... cool!

Thanks for sharing.

Here are some
notes
I've made on manometers.
