Can't tell by your picture, is the ball thrust bearing "bad"?
Just remember, the governor spring tries to pull the throttle butterfly open, and centrifugal force acting on the weights "fights" the spring and holds back engine speed.
When the forces are equal at a given setting of the throttle lever, that is the engine speed the governor will maintain, within reason.
A broken spring means that speed won't rise above idle, MOST other governor problems will result in "overspeeding", "poor response" is typically caused by the mechanism being "sticky"
Be sure that the weights can move freely and that the "fingers" on the weights and the "fingers" on the "fork" are smoothly radiused, and don't have a noticeable "flat spot". If they DO, that will affect governor response.
Also, be sure you assemble the spacer, the two bearing races, and the bearing itself correctly (25 and 26).
Check the condition of the spring (26) inside the hollow front end of the governor shaft and be sure the "governor shaft bumper pin" (30) is in place.
Also check the condition of the "governor bumper spring" (27) partially inside the "governor bumper spring body" (28).

Today's Featured Article - Tractor Hydraulics - The Basics - by Curtis Von Fange. Hydraulics was one of the greatest inventions for helping man compound the work he can do. It’s amazing how a little floor jack can lift tons and tons of weight with just the flick of a handle. What’s even more amazing is that all the principals of hydraulic theory can be wrapped up in such a small package. This same package applies to any hydraulic system from the largest bulldozer to the oldest and smallest tractor. This short series will take a look at the basic layout of a simple hydraul
