Metal plug is an indicator of the problem with the ONAN carbs. Sealed up to be non-tinkerable. That said, that 90* "corner" one of the techs told me about is probably adjacent to the screw you can't get to.
Governor Spring simply can't hurt. There's also a tiny spring or two designed to keep any lost motion out of the linkages on top of the carb (throttle and/or choke) so I'd guess it'd run sloppily if one was missing or disconnected.
Well, it has an automatic choke (thermostatic coil) to richen it for starting and warmup. So sure, Mixture does change with outdoor temperature and probably the operating temperature of your genny.
