Governor wont engage case sc

I cant get governor to engage like it should that is at all when its under a load or applying the brakes. I installed it per the manual but still got nothing not a lot of info in archives. It has a new thrust bearing in it probably didn't need it I had the same issue before I tore it down everything else looked ok to me.

Just a note: First a word of Thanks to all the folks who have helped me through this project Your expertise was invaluable and I'm grateful to each and everyone of you. I had to move the tractor so haven't finished it as of yet but it started right up first try after having it tore down for almost 2 years.
Thank again Byron
 
With the engine not running, pull the throttle open. It will pull the governor arm towards the rear of
the tractor with the gov spring. Now grab the gov arm, that reaches across in front of the block and you
should be able to push it smoothly fwd against the spring. When the engine starts centrifugal force will
pull the arm towards the front of the tractor, slowing it down, the further you pull the throttle back,
the more tension is applied to the spring thus holding the throttle open, less throttle, less centrifugal
force, less engine speed. They are really simple, nothing more than a large lawn mower type governor.
Figure out how it works and you'll be able to identify the problem. Either internal in the government or
external in the spring/linkage adjustments.
 

If the SC is the same as most other Case governor setups, disconnect the governor rod from the carb, put the throttle wide open and tilt the carb lever to wide open and adjust the rod length til it just fits. Obviously this is without the engine shut off LOL, if the governor has a tendency to surge you can adjust the rod to minimize it HTH.
 
Thanks guys I drove the tractor about 5 miles from here so I will check it out in the morning. This thing did work at one point I remember even at full throttle it would increase RPMS to get through tough spots. So I assume there should be some remaining room for the governor arm to advance farther forward. I'm a little confused does it or should the carb throttle plate open more when the governor kicks in or is there an increase in vacuum that should draw more fuel. It just seem like the Throttle adjustment screw via the carb linkage stops the governor arm from being able to open the throttle plate any more than what you have preset it at.
Thanks for any insight you may have

Answered my own question got it!
 

Curious, what did you find, the flyweights in the engine fly out and balance against governor spring pressure to control rpm, as the engine loses rpm in a pull the spring overcomes the weight of the spinning flyweights and pulls the weights in and the arm that connects to the carb shoves the plate in the carb open increasing the engine power output to match the demand. Intake vacuum is affected by throttle position and engine load but not a cause of controlling rpm, that is all mechanical.
 
Yea I just had to readjust the carb linkage and the Collet also the length of the throttle linkage
