A little effort with some WD-40 and a red scotchbrite pad and it had them looking pretty decent. There were still some marks left when I finished cleaning them, but I could not feel them. Again, Im not sure how this will affect how it runs, blow-by, or anything else related to efficiency or longevity, but I am hoping for the best at this point. I would be curious to hear if anyone has any experience with running one of these with cylinders that look like this.
One of the better ones
One of the worse ones
