I have been driving it for a few days, and so far, the oil temp seems to sit right around 210-215 via my gauge in the taco plate and verified with my laser thermometer. It is currently in the 50s-70s here. I have also checked my head temps after a short drive and idle where I could get the laser on it, and it has been around 360-390.

It is still really hard to start when cold, though. Used to fire right up, even after sitting for a month. I did find that I had mislabeled the thermotime and aux air plugs, so they were initially swapped, but even with them swapped back, it still takes a ton of cranking to start when cold. It seems to be fuel related, like maybe the cold start valve has suddenly failed, though I didn't touch it. I should mention that I tested the Temp II sensor and the aux air, and they both check out.

I had to replace the thermotime switch plug with a spare. Is it possible that I have the wires swapped? I wouldn't think it would matter as it is simply measuring resistance, right? Kinda sucks that all these plugs are the same.

One good note, I had a pretty erratic vacuum reading before, now it is a nice steady 9-10 in/Hg at idle. I know, low, but this is a high mile air cooled VW.

Check to see that critical red/white wire is actually attached to starter spade terminal. It goes to double relay. It turns on fuel pump during cranking AND supplies voltage to the cold start valve.
