Well darn, thought I'd figured it out. It's really got my curiosity up now. That's why I was looking for an exploded view of the throttle assy.. to see if there is some sort of spring attached to the lever under the dash. Thereis normally some sort of friction disc under there, with spring tensionadjustment on others like my 2000 Ford,but it's mainly to hold it in higher rpm positions, to keep it from dropping back towards idle.
Otherwise, I'd have to remove the throttle linkage from the Gov. If it snaps to the WOT position, it's definitely internal. First thing I'd check would be the flyweights, which I'll assume you did. With the cover off, they should move freely. If those are free, then I'd check parts #4 through #17, moving #6, while holding some tension on #5. It should move, but spring #10 in the connecting link. If there is some slop in movement between the two, then I'd take a close look at parts #9. 17, and 4. Especially 9 & 17 as to how it attaches to #6 levers shaft. They should have a hole, with flat sides to lock it in place on that shaft.
This Gov. is different in respect to that portion on the governor's on the C-113/C-123's I have, as the throttle lever the throttle rod hooks to is on the outside of the Gov. housing, and has a set of forks that ride against the thrust bearing.
I am rather confused as to how lever #6 is held in place, compared to lever #5 in this exploded view of the C-123 engine I have Schematic, Manuals, Specifications and Diagrams for Governor and connections, 100, 100hc, 130 and 130hc tractors | Case IH | MyCNHi US Store . On the C-113/C-123's, there is a nut. and lock washer to hold them in place, (10 & 11) whereas the exploded view of the C-146 does not show them. Maybe it was left out, when drawn up, but seems there would need to be something to hold 9 & 17 in place on that shaft, and in the housing. If in fact there is a nut and washer on yours, it could have loosened up, and allow #17 to move freely on that shaft, without controlling/transferring the Gov.'s actions to lever 5. All of that assy. should be easily seen, and moved with the cover removed.
