Re: G3516a3 throttle actuator swinging

On the G3516 A3, most of the engine governor settings are not changed from the default, which is (0) zero.  If you want to try, reduce the settings and see what happens; does the governor instability slow down?  The default settings usually work on this engine so you may have an issue with unstable fuel supply or something else.  Does the compressor have a suction controller on the inlet gas to the compressor?  Sometimes an unstable suction controller can cause the engine speed to swing.  What is the engine serial number?
