QUICK VALVE SPRING CHECK
For a quick check or if I don’t have a Spring Height Mic that is small enough, I use a telescoping gauge to get the height off the head. Then I have various Valve Adjustment Discs I can use to simulate the retainer thickness and I don’t have to re-adjust the snap gauge for the retainer thickness. I just set the gauge on the disc.
