Never had a no start problem, it would always start, but die off. Couldn't ever keep the thing running. In the video it would almost immediately die right after you start it. I found out I forgot to hook back up a vacuum hose that goes from the valve cover to the intake manifold. Now it runs about 3 times as long before dieing off. I'm almost certain now I have a mysterious vacuum leak that's eluding me. I could be wrong, but it's about the best lead I've got to go off of now.

Thanks for the tips, I'll def keep those in mind and take a close look at them
