What are the specs of the Short Travel lifter? The Reduced Travel is .093" travel, preload .035" +/- .010".
It is a rain day so I think I will bump up the preload from the current .025" to .035".

The ST21120PR has .058” of effective plunger travel. I believe Johnson wants the preload towards the bottom of the travel on these.
