I'd say it could be possible that when the engine is running it could drive the governor gear off the cam gear with that much play. Did you reinstall the shims on the correct side of the cam shaft?

Which timing mark on the crank did you use when you reinstalled the crank and the cam?.
It happens... I had a 7 hp have the same issue,changed out the gov gear with a known working one and it fixed the problem,who would of thought a metal one going bad.

I've read this over a couple times now, the governor gear should push itself towards the block due to the helical cut. there should be a shim that goes between the block and the governor gear. the cam would push to the bearing plate side of the block. I'd find it odd if the governor gear was loosing contact with the cam . I've shortened cams before and shimmed them on the opposite end to advance cam timing. you have to take allot off to start to come off the gov gear. it almost has to be an adjustment issue. I know it can be difficult to hold the carb open, rotate the gov shaft and tighten the bolt on the gov arm without anything moving.

To answer a few of your questions:
1. The crank/cam timing marks are correct. 2. The shim is behind the governor. 3. There is no binding of the linkage anywhere. Everything moves freely.

I have decided to step away from this one for a while. I have no ideas at the moment as to what might be wrong, and have several other projects waiting so Im moving a few of them through.

might have an idea on this one. just ran into it this afternoon. when you tighten down the brass nut on the outside of the block does the cross shaft get stiffer? if so take the brass nut and file off a little on the threaded end till when you install it you have a little movement back and forth. it seams as you tighten down the brass nut it starts to pinch the cross shaft because of the spacer being in there.

I am dealing with this exact issue with my 123. No throttle control at all above idle and it races away. Been through the service manual governor adjustment procedure a bunch of times and am comparing everything to my 127 set up as well which governs out fine just to make sure. I really hope we figure this out too.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
