It really is just that simple, kids. Seems like every few years someone posts a "better" way, which is really just more complicated and/or more expensive (if you buy their nifty tool).

The world's simplest way to do this: Don't even try to "check" any of them. Simply loosen the lock nut, then loosen the adjustment screw until the rocker moves enough to easily place the feeler gauge in the gap. Hold it there with one hand and, with the other, put a screw driver in the slot and push the adjustment screw down onto the feeler gauge until it makes firm contact. Then turn the screw driver until you take all of the play out, tighten the locknut, and you are done. This takes literally a minute or less, and no skill or "feel" whatsoever. And no elaborate, funky tools.

Way too many people let this simple procedure intimidate them. The whole question of what is too loose vs. what is too tight gets way over thought. The tolerances are very generous. If you can slide the feeler gauge without undue effort, and the rocker doesn't move with the feeler gauge in place, you are good to go. No need to overthink this, or to resort to weird little tools.
