Case 430 governor issues

C

Case 440

New User
My 430 gas tractor was over revving, surging at constant load, and slow to throttle up when load was increased.
I took the timing cover off to see what was going on, and the governor weights had started to cut into the timing cover.
Everything seems to be moving freely, and even though the gears looked dry, the oil passages were not plugged.
I have replaced the double springs on the throttle lever side of the governor actuator.
Any ideas what would cause this?
I adjusted the carb and linkage.
How much oil should you see on the timing gears?

It seems like the domed part of the governor with the shaft that goes into the end of the camshaft might be controlled by oil pressure.
Would over revving cause high oil pressure that would push that shaft out and over extend the weights, there by hitting the case?
Or should there be some type of end stop?
