    Yea, lot of timing lights act kind of whacky with a Multi Spark system like your MSD. I don't think you have a timing issue. Something is broke somewhere, just have to find it.

    I did not have the throttle open. I will try that tomorrow! But I'm still not feeling good about having one at 35 on one reader and 0 on another reader...

    Ya that sucks dude. That's probably the problem. I'd say intake valve

    Not good that it happened, but good that you found it.
