Thanks for the replies. Are we all thinking the same thing? Drop the sump and see what's broke.
The governor is what SLOWS the engine so if an engine will not run slowly then the governor has failed.
The failure can be as simple as the shaft coming lose or as complex as the governor requiring replacement.

Also, could I be missing a third spring or linkage that I am not seeing in pictures or schematics? I am not understanding how it knows to back down the throttle from high to low. I haven’t been convinced that I’m not missing something.

From what I can tell about governors, there's got to be a jeanie inside the block that makes this all work.
