Governed Speed (RPM) Limits

In order to comply with specific top governed
speed limits, Briggs & Stratton supplies
equipment manufacturers (OEM)s with engines
that have adjustable top speed limits. These
limits are set to OEM specifications.
The top no-load speed limit will allow no more
than the desired top governed speed limit when
the engine is operated on a rig id test stand at our
factory. However, the design of the equipment
being powered can affect engine speeds.
Check top governed speed with a tachometer
when the engine is running on a completely
assembled unit. The equipment should be
operated at no load when making this check.
If a governor spring must be replaced:
• Consult the appropriate Illustrated Parts
List.
After a new governor spring i s installed, check
engine top governed speed with an accurate
tachometer and adjust as required.
