Governed RPM Limits

To comply with specified top governed speed limits, Briggs & Stratton supplies engines with an adjustable top speed limit, which the equipment manufacturers set to their own specifications.

Top governed speed should be checked with a tachometer when the engine is operating on a completely assembled unit. The equipment should be operated under no load when making these checks.

If a governor spring must be replaced, consult the appropriate Illustrated Parts List for the correct part number.

After a new governor spring is installed, check the engine top governed speed with an accurate tachometer, as noted above, and adjust as required.
