My dad came home from work early to check it out. He told me to go fill up the gas can (which I emptied into the oil tank). I ran out to get it, and when I came back, he had it running in the driveway.
So he saved the day, basically. I'm not sure what he did, but whatever it was, it worked. He said I wrecked the air filter, so he has to replace that, but the engine was ok.
