All fixed!

Transmission adjusted, finally. I got a new TV cable from the parts store, installed it, and it was still screwed up.

Turns out the steel inner cable was way too long. I had to shim it with a pipe fitting and small clamp. After that, I was in business. Shifts in the proper places. Downshifts on demand. Shifts at 4000 rpm under WOT, just like it should.

Powertrain is done.

I also fixed the grabbing right rear brake. It would grab hard when cold, resulting in noisy skids and the like. Half a can of brake cleaner and some sandpaper to get the contaminated brake pad material off the shoes and the inside of the drum solved the problem. The fast idle valve is also working now.

That out of the way, I'm turning my attention to my house. I've installed new vinyl and carpet in the basement, and new vinyl and new paint in the kitchen. I've cleaned the grout in the bathroom, too. Pretty soon, this place my look like less of a dump.

Updates...

Been doing a lot of running around the past few days. Items that need attention:

TV Cable. It's fucked. The clips that snap it into the throttle side are all mangled. It's sort of flopping around, I think it may be contributing to my issues getting it adjusted.

Timing. It's pinging above 3100rpm. I think I need to take a couple of degrees out. I also think I may need some new plug wires.
