Valve spring tester, running valves

The LSM spring tester is a fine piece of equipment. You do have to adjust it to your type of rocker arm. It comes with a good set of instructions. You have to calabrate it to a known spring that has been tested on a good quality bench tester. Then you check the spring with the LSM unit. There are shims you add or remove until you get the same pressure reading with the LSM and the bench tester. Once its calabrated it will give you excellent results. Very accurate
