"Also I’m wondering if the governor is necessary? Can I remove it and be ok ? Or should I clean it up and reinstall it."
You should be able to remove the governor.
You might have to adjust carburetor linkage rods/etc.
Use a bakelite carburetor spacer and the correct gasket with opening in the gasket oritated to the opening on the base of the carb.
Wait to hear from a Big Truck owner - it has been a long while since I removed a governor,
