Adjustable Rocker Arm HELP!!!!!

Make sure the lifters are all the way down in the bore. When they are down
Rotate the push rod in between your fingers. untill the rod has a slight drag.
That is when you have zero lash. Tighten the rocker nut about 1/2 turn and
tighten the lock nut. Do this on all the rest when the lifters and you are done.
Good luck, Green Duster.
