I went to adjust some of the slop out of the steering, the lock nut proved particularly stubborn. I tried PB blaster, etc to no avail. I ended up removing the battery and the battery tray, along with the boot off the number 1 plug. Then I was able to slip a socket over it, put a breaker bar on it, and get it loose. I would tighten the screw, check the wheel, tighten, check, etc. I found about 1 1/4 turns were needed to get it where I expected it to be. There is still some slop but nowhere near what you see in the video.
Next day I looked at the choke and reset it to the middle adjustment. It idled much better, but seemed to come off a little early. I'll have to adjust it some more, but that will have to wait for it to cool. Since it was warmed up, I took it out for a brief spin. The steering was much much better. At no point did I feel like it was out of control guessing. Even at 50+. It still feels a bit over boosted and I might adjust the shims but for now it is at least drivable without a feeling of sheer terror.
