Spent some time today doing more tuneup work, and also watched the John Twist YouTube video on SU tuning.
I was able to use the piston-lift method to feel out the mixture, then cleaned the plugs (small wire brush and a blow-clean with the air hose) and went for a drive. Here's what the plugs now look like.
Cylinder #1 (front):
Cylinder #4 (rear):
These pictures were taken in my garage, but I also checked them on the side of the road after shutting off the car while under power. Looked essentially the same.
Am I getting closer?
