when i got my first 4wheeler or dirtbike ever (blaster) the guy and his son came and dropped it off at my house onenight, i was all gungho to go rip it and it ran for like 10 feet and then bogged out and died and wouldnt start, i thought they screwed me or something, therew was still a tiny little bit of gas in it from the looks of it, but sure enough, i put a gallon in started right up and ran fine
