Tonight I removed the springs and valve retainers from the mild-vinegar solution (it worked) and cleaned them up. Next I worked on the 4 remaining valves and valve seats, and did as good a job as I could do.
I will hand this over to my mechanic (Calle) to see if he can get the entire cylinder surface leveled out better than it is now to remove some of the pitting on one of the pistons.
The mild vinegar sure cleaned these up !
And here’s the finished result..
