IIRC, it's a complex process involving a lot of very careful measurements and delicate adjustments
to the linkage connecting the valve stem to the lap-and-lead (combination) lever of the valve gear.

I was watching when Bob Slover adjusted the valves on #2472 in May of 1991, but didn't really get
a chance to learn exactly what he was doing. (See [ngdiscussion.net].)
