Engine overspeeding, hunting or not holding RPM?
Governor faults often cause unstable engine speed, overspeeding, hunting or engines that won't hold RPM under load. Testing and calibration find the problem before parts are replaced.
Common signs your governor needs checking
- Overspeeding or not holding set RPM
- Hunting or fluctuating speed
- Unstable idle or surging
- Speed too high or too low under load
- Poor performance or fuel economy
- Slow response to load changes
Request a governor inspection

Many can be repaired and recalibrated, which usually costs less than replacement.
