Cylinder 8 not firing

Numbers seem good.

- Change # 8 spark plug and wire; you can swap them into another cylinder to see if the problem follows them
- Actually measure the lifters/rockers for #8 to see if they are moving as much as the others; could be a collapsed lifter or bad lobe
- Run a leak down test (with out expecting much bad)
- Check # 8 exhaust port for a mouse nest (getting desperate now...LOL)
