Adjusting the valves is done by turning the engine over until the exhaust valve just starts to open; the intake valve is then adjusted. Loosen the nut, then while spinning the pushrod with two fingers, tighten the nut until the pushrod stops spinning easily then tighten the nut another three-quarter of a turn. Turn the engine until the intake valve opens then almost closes and adjust the exhaust. Repeat for the rest of the cylinders.
