CHAPTER 2 8354/8404
b. Operation of Governor
1) At start
The steel ball (13) has no centrifugal force. As the fork
lever 1 (4) is pulled by the start spring (1), the control
rack (14) moves to the maximum injection position. At
start, the sufficient injection of the fuel enables easy
starting.
2) At idling
At the idling position of the speed control lever (15), the
governor spring 1 (2) is free and the governor spring 2
(3) does only act slightly. The governor sleeve (12) is
pushed leftward by a centrifugal force of steel ball (13).
Therefore, the fork lever 1 (4) and control rack (14) are
moved to the left by the governor sleeve (12) and then
the idling adjusting spring (16) is compressed by the
control rack (14). As a result, the control rack is kept at
a position here a centrifugal force of steel ball (13) and
forces start spring (1), governor spring 2 (3) and idling
limit spring are balanced, providing stable idling.
IMPORTANT:
• The idling speed has been factory-set. The idling
adjusting screw (20) and spring (16) should not be
disassembled and readjusted.
