Like jet airplanes, space rockets work on a principle called action and reaction (another name for Newton's third law of motion). The massive force (action) generated by hot gases firing backward from a rocket's engines produces an equal force (reaction) that pushes the rocket forward through space.
When engine revs up, what does the governor arm do? Does it move forward toward front of engine, or does it push toward the carburetor? From the way it is made, it looks to me that it pushes toward the carburetor. With that said, it should be all the way forward when tractor is idling and should move rearward when engine speeds up.
