This is a "bonus" video, extra content that's a bit of a shambles but might be of interest to some viewers who like technical stuff. I recorded myself trying to diagnose and fix the throttle linkage issue on my narrowboat (basically that the throttle would not return to idle without also disengaging the gearbox, whereas I needed the engine to run at idle while still in gear) and it's very much a "stream of consciousness" recording rather than a how-to or any kind of tutorial.
