If you started an unknown engine without checking the oil I would imagine you didn't bother to replace the old fuel either. It would be a good idea to, to avoid stuck valves.
Never thought to check because
1. The guy I got it from was a total Saint of cars, little did I know when I went to check it out after finding it on Craigslist, I would be spending the entire day at his place checking out all his projects from his out-of-home restoration shop... So the excitement of starting it up was over thrown my concern of doubt in his skill.
2. He filled er' up from almost empty to full for his delivery trip a handful of days ago
