timing light??

I use an MSD light.

You can't use a dial back on an MSD.

Ya know I've read this before. I have a Craftsman dial back type that I use. I'm running the MSD digital 6AL. I've experimented with the light on 0 and checking it on 33 degrees. Dead on either way.

I wonder though if it is accurate.....like to try a non dial back to see if it's on the money.
