Well it helped a bit. The thing has steadied its output considerably, but not entirely. The whole chassis still shakes, enough to make the entire generator move slowly in one direction, and the light I have attached to it does not shine consistently - it dims just a bit as the engine speed fluctuates. It's still not nearly as steady as a lawnmower engine is. Of course, I don't know really how steady your average generator is supposed to run, as this is the only generator I've ever seen.
What about fuel injector cleaner? Is that safe for this kind of engine?
Oh yeah, checked the oil level - it's ok.
Update: I futzed around with the governor and that spring thing (or maybe that is the governor, I don't know), and now it's running almost completely steady. About every 20 seconds it'll slow down and shudder slightly, but other than that, the light I hooked to it stays quite steady. It would appear that this thing is ready for some action.
Thank you to everyone who helped here. I'm never really one to mess around with gas engines. Computers are simple to me. DC current - don't short anything out. Engines - they all look like things Rube Goldberg came up with in his worst nightmares. And they come with a tank of flammable, volitile liquid strapped to them.
