Yes and the governor spring may be different too.
There are probably a lot of little things that will need to be swapped from industrial to the tractor engine. For the gov. it depends on the RPMs the engine was set up for and the gov. settings and spring etc.so will take some real knowledge of it,s setup to change over to a tractor.
If you can post the RPM rating of the engine I can get you the governor setup from the rack setting charts.
