- Disconnect rod (9) and spring (10) from lever (11). Adjust housing (5) in order to obtain a lever force at knob (2) of 30 ± 4 N (6.74 ± .9 lb).
Note: Knob (2) should not move more than 30 mm (1.2 inch) while the setting for the lever force is performed.
- Move governor control lever (2) to the HIGH IDLE position and install spring (10) .
- Move governor control lever (2) to the vertical position. Adjust stop bolt (3) so that the bolt contacts the governor control lever. Back off stop bolt (3) by one turn and lock in place.
