    If you'll try it again, I believe I can get you headed in the right direction.

    With sparkplugs out and alternator cover off...

    1. Use two feeler gauges (bent at 45 degrees). 1 under each adjustment screw at the same time for that rocker arm.
    - this will keep the cam from rocking while adjusting the valves...which will lead to an improper valve adjustment

    2. After adjusting each screw, remove the feel gauges and rotate the engine until the valve pushes up on the adjustment screw, putting pressure on the adjustment screw. Now you can tighten the adjustment screw locking nuts without the adjustment screws turning.
    - Bonus is that after rotating the engine, it pushes the adjustment lock nut higher in the engine making it easier to tighten.

    3. Rotate the engine at least 2 complete firing cycles to "set" the valves. Re-measure the valves (using both feeler gauges at the same time) and change if necessary. You may find that one adjustment screw measurement changes every time after you rotate the engine. Change the initial setting until the screw measurement(after rotation) is in spec.

    4. Rotate the engine until the adjustment lock nuts are high in the engine and torque to specs.

    Only 3 more to go...

    PS. Properly adjusted valves will clatter when cold and will go away or only clatter slightly when warmed up. If you have a loose tensioner chain, you may not be able to hear the valves clatter over the chain noise.
