okay, ever since ive had this fourwheeler its had flooding problems. so bad that when i have the choke on sometimes fire comes out of the muffler. a few months ago, i left it at my cousins house and came back to get it, its was rolling white smoke and was kinda jumping but not really moving, I was really mad so i left it to sit.. about a week ago, i went and checked the oil, it was overfilled and smelled like gas... What could this be? My dad asked a guy who works on engines and he said to drain/change the oil and it should be fine. but what do you guys think?
