I hate sounding like a novice, but I'm not clear on what this part is. On my picture, it's circled in blue. Also, there is what appears to be a small filler or drain plug on the right side. Does a fluid go in there?

That is the Governor Housing that you have circled, the plug with the lock nut is for the bumper spring adjustment.

Re: What's this part on my 67 Lo Boy?
Hi,
The adjustment on the front side of the governor needs no adjusting if the governor is working right when the engine is running. Don't turn it. It is not an oil plug.
The governor is lubed by the engine's motor oil, there is nothing to lube, except the linkage on the outside of the governor. Lube all the moving parts with an oil can, from the throttle lever to the governor, and the moving parts from the governor to the carburetor.
One place that commonly gets tight is the pivot in the pic below, the end of it is where the cotter key is in the pic. The shaft is solid on the governor. Oil where the cotter key is. You probably have to reach in from the left side, use a light if you need to. It is number 11 in the parts pic above.
The other end of the pivot can be seen in your pic above, below where the throttle rod attaches. Picture from TM Tractor.
The throttle high speed stop bolt looks a little too far out in your pic, not sure though, if it's been replaced with another length bolt, it might be a different length than original. You could hook up an engine test tachometer and check the speed. Adjust the bolt so the throttle lever stops going forward at 2000 RPM, the manual says.
That speed is not for Cubs in the 1940's and 1950's that said a lower RPM on the serial number plate. The bolt is number 13 in the parts pic above. Loosen the lock nut first so the bolt will turn, if it needs adjusting.
The slow idle speed should be 475 RPM, the manual says.

Thank you to both people who replied. Makes sense now. Again, I have a much better understanding since joining this board and talking to all the helpful people here.
