The governor is being over ridden by using the prop lever to change pitch. thats why the engine slows down when the prop is cycled. the engine will try to maintain the speed it was running at due to the manifold pressure being set and therefore the engine is required to do more work, resulting in a higher burn temprature as the piston is harder to push downwards and the combustion process is held in the cylinder longer before being released.
