I did a weekend of trail riding last weekend. When I got my quad home i cleaned it up, pulled the air filter out and put it back it. Has not run for a week, My wife took it out this evening for a couple laps around the house, barley getting on the throttle. Gas was low but not on reserve, she went up a hill and it died. i added gas anyways but now it wont stay idling. It will start up with choke on but as soon as i turn choke off it dies. Any thoughts out there? thanks!
