Thanks, that's good to know. This is a basic, older Generac GP5500 and I couldn't figure out how to get the carb apart, it really seemed pressed together. Maybe that generator already had it's replaced, as the replacement I got looked identical.
Looks like the OEM part is only $50-some, so worst case I'll get one of those down the line, but the generator was running at a friend's house for three days straight a few weeks back and no issue, so hopefully it'll keep being good.
The emulsion tube might be pressed in on that carburetor. 99% of the time there's some deposits built up from old gas and that's why it doesn't run / doesn't run well. Use thin wire or a carb cleaner kit or a torch tip cleaner kit to poke the junk out of all the parts you can remove/access, and use a can of carb cleaner to spray through all the channels you can't otherwise access.
