| SHEET B SETTING OF CONTROL ROD FROM GOVERNOR. *THIS SHOULD BE SET AFTER THE THROTTLE HAS BEEN SET.* DISCONNECT SPRING S. DISCONNECT ROD P FROM ACCELERATOR TO THROTTLE (SEE SHEET A). RAISE THE EXTREMITY OF LEVER L UNTIL A POINT OF FREE MOVEMENT IS REACHED A SMALL DISTANCE FROM THE TOP OF ITS RANGE. (THIS FREE MOVEMENT IS DUE TO BACK LASH IN THE INTERIOR OF THE GOVERNOR). ADJUST THE LENGTH OF ROD R WITH LEVER L IN THIS POSITION UNTIL ROLLER A IS JUST CLEAR OF ARM D (SHEET A). DEPRESS LEVER L FULLY AND OBSERVE THAT ROLLER IMPARTS FULL 40° MOVEMENT TO THE BUTTERFLY BEFORE RESTRAINED BY LEVER L REACHING ITS LOWEST POSITION.
