When the engine was on the stand I adjusted the valves 1/2 turn past zero lash. This was done with the intake off where I could watch the lifter plunger get depressed. Would one full turn past zero lash be better?
You should only have 2 - 2 1/2 threads showing on the adjusting screw at the bottom of the rocker when you have it properly adjusted. No more than that.
