Ok I read couple of different papers regarding how governor works. Still confused. Say an egnine support to run at 3500 RPM.
Is this true: when the engine load increases, RMP drops, governor moves arm(due to RPM change), arm pushs the throttle opens more, engine back to the same speed. So no matter what load the engine has the RMP stays the same.
If that is true when does the governor spring comes in to play? How is the engine idle speed accomplished if governor suppose to set the engine speed to 3500 RPM?
