Help! Wiped cam lobes? - Video inside

So the engine is together, everything looks pretty good. I went to start it for the initial break in and i'm having a problem getting juice to the coil. I got gas to the carb, and it wanted to start, but kept stumbling. It looks like i'm not getting 12 volts at the coil. my indicator light shines brightly when I know it has 12 volts going through it, but is notably dimmer when touched to the coil. I'm not sure how to go about tracking this down. Its had spark related problems before, first it was the pickup coil, and then I thought that it was the wiring harness getting covered in coolant after a leak. (It was fine after it dried out)

Any suggestions? I don't want to risk messing up the cam trying to start it over and over.
