NOTE: Valve spring pressure will tend to rotate the ywheels out of position. One method to hold the ywheels in position is to have an assistant apply the
rear brake to secure the ywheels during the ignition plate alignment procedure.
The engine must not be allowed to rotate while the alignment pins are in place. If the engine rotates while the alignment pins are
installed, permanent damage to the components will occur.
