Troubleshooting
If engine hunts at top no load speed, check
governor adjustment as follows:
1. Stop engine.
2. Move equipment control to “FAST” position.
3. Disconnect governor link spring and link.
4. Rotate throttle wide open position.
NOTE: Position of governor link must be within 1
mm of center of hole in throttle (Figure 27).
Figure 27
• If dimension is greater than 1 mm, perform
governor adjustment.
• If engine continues to hunt at top no load
speed, decrease governor sensitivity by
moving governor spring to next hole on
governor lever (Figure 28).
NOTE: Moving spring away from governor shaft
pivot point decreases sensitivity. Moving spring
towards governor shaft pivot point increases
sensitivity.
