Welp, looks like it just needed a good bleeding. Got fuel dripping from all lines, connected em back up, and she fired right up. Ran a bit noisy at first, but I took her out and was immediately impressed. The off the line smoothness and power is unbelievable. She was puffin out some pretty good smoke at first, but after a few good runs, all that cleared up. Still has a nailing on one cylinder at idle before it warms up. Seems to be the same cylinder as before, but that doesn't worry me.

Also, after giving her a good drive, I checked my blow by. While not totally gone, it is much less, which made me quite happy.
