So it still drops in rpm and stalls if u put a load on the engine and hunts when u try to rev it back up so I thought ill reset the governor. Loosened the bolt start to turn the shaft and snap! I could hear something fall down to the oil pan. Not good.
Is this going to be a big pain to replace the gear and cross shaft?

Sounds like the cross shaft tab broke off. Better that it did this now then when the motor was running and break the rod.
The Cross Shaft and governor gear are the "first" things to be put into a motor and the last things to come out due to their location. It's not a really bad job to break the engine down to get to them tho. If you get in that far, I would replace the governor gear, and put a new cross shaft and cross shaft bushing back in.
Download the Kohler service manual located in the Tractor Technical library. It will show you how to disassemble the motor and the governor gear location.
Here is a pic of my 12hp motor with the new gear installed.
