To maintain engine stability at the minimum speed setting, a small amount of droop can be added
turn the DROOP adjustment CW. At the maximum speed setting the governor performance will be
near isochronous, regardless of the droop adjustment setting.
Contact for assistance if difficulty is experienced in obtaining the desired variable speed
governing performance.
