Manual Extract: Setting Valve Lift

1. While pumping fuel through injector, hold the pressure adjusting screw and slowly turn lift adjusting screw clockwise until valve ceases to open.

4. Recheck the opening pressure. Note that the lift is set before checking spray pattern and chatter because the amount of lift will affect these characteristics.
