135 massey ferguson governor question

When putting the governor bearing on the cam and nut is torqued and you sliding the bearing cover on ,when the stem of it goes into the cam should it slide in rather easily or have just a little resistance. Installing by hand not tapping with a hammer or anything.
The front timing cover has a spring made on to the inside. Is it supposed to be straight or have i little bit of a bend in it. Cant find any information on how far it is supposed to be off the cover. When you screw the side screw in it has that tapered end and when it touches the spring it basically moves the spring out from the cover. Not really understanding how it works. I can understand the components. But why the screw in the side cover ? Does the bearing cover with the stem slide in and out of the cam ? Oil pressure must push it out maybe. I saw a video on youtube about adjusting it and why i took mine apart is when the man cranked his up with throttle linkage off his governor rod was working back and forth. I had put a clutch in mine and i was putting it back together and the throttle linkage is just wore out. I cranked mine up while doing some adjustments and my governor rod didnt do a thing .Thats why i took it apart. Everything looked great but that bearing cover was a little stiff coming out so im thinking maybe that could have been my issue. Is that a possibility?

The fact the bearing cover was a little stiff can effect how it works.

That spring and screw is the bumper spring, and adjustment screw. so that needs to be set also.

That stem MUST slide EASILY in the cam! The hole is vented, NO oil pressure is used to "push" on the stem. The flyweight balls go in/out as needed against governor spring to adjust governor as engine load changes. The bumper spring is seldom needed IF the carb to governor arm is set right. If engine speed surges, SHORTEN the rod length as needed. If governor is lazy LENGTHEN the rod as needed. This works on any governor that "pulls" the carb throttle plate open. If the governor "pushes" the carb open, then the rod length change adjustments are reversed.

Thanks you very much for that info

Thank you for that info
