Make sure both valves are closed when you adjust them. Use a feeler gauge to check the clearance. If it needs to be addressed, loosen the lock nut and move the adjuster up and down until you fell a nice drag on the feeler gauge and there is no wobble on the feeler gauge.
Do this to all the valves. Then torque the lock nut to 22 foot pounds.
