Help. I am working on a TO35 that the previous owner had installed a new governor which does not work. The previous owner suffered from dementia at the time so we are unsure if the proper procedures were followed. I have attempted to adjust the linkage following the I&T manual without success. The tractor immediately runs wide open. I have the timing cover off looking at the governor. I believe it was way over torqued and you have to apply pressure to get the balls to move outward and then pop when they move to the outer position. Is this normal? Should I just order a new governor and start over?

I'd get a new unit even if this one frees up when removed. They are not really that expensive when considering the effort required to access. The unit, which is the same as the Z-129 engine, comes with a thin washer which is used in the smaller engine but not in your Z-134. (I am pulling this up from memory, have an IT manual and follow the instructions). It is important not to over torque the large nut as it can lead to the camshaft breaking.

What I understand, looking at the front of the cam gear, when the
governor ball cage is seated against the front of the gear, it must sit
flat. If there is space between the cage and the front of the gear, it
needs the shim. If it sits flat against the gear, it does not need the
shim.
It must tighten down securely without distorting the part.
Also be sure the stem slides freely in and out of the hole in the end of
the cam. There is a small vent hole that must be clean so the pin is not
dampened by trapped air behind the pin.
Here is some more info.
