Rich, My Yanmar 3HM35F has a governor and it works exactly like all three of my home generators and the one I've see on an old Lister diesel. Basically the throttle pulls in opposition to the governor. When you set the idle speed you are adjusting a screw to push or pull in opposition to the governor and in favor of the throttle.
This is also similar to the set up found on the 3.5 megawatt diesels I have at work. The only engines I have experienced on which I can't recall any governors is my lawn equipment. I just assumed I hadn't found it yet ;-) I just can't figure out any other way for the engine to automatically cut fuel as it over speeds in neutral.

If more sophisticated control is needed, such as a generator that has to maintain a constant speed to keep the AC frequency constant, a governor of some sort will be added. Most marine gas propulsion engines do not have governors as the loading with a propellor is fairly constant. > > > Rich Knowles > Indigo.

Without a governor what is the feed back loop that prevents over speed and under speed? Many people mistakenly call rev/speed limiters governors and visa/versa. > > Josh > > -- > When privacy matters. > http://www.secure-my-email.com > > On Aug 20, 2013 11:38 AM, "Knowles Rich" <r...@sailpower.ca> wrote: >> >> I was not aware that an Atomic 4 has a governor...?
