Valve Clearance: Adjustments

1. Position cams so tappets are in the base circle area on cylinder to be adjusted.
2. Loosen adjusting screws until a distinct lash between roller arm pad and valve tip end can be noticed. Tappet plunger should now be fully extended.
3. Screw in adjustment screws until rocker arms slightly touch valves.
4. Turn adjustment screw in an additional 1-1/2 turns (equivalent to .079 inch plunger travel into lifter) to achieve normal operating position.
