I have a 1993 Polaris Trail Boss 350L 2- stroke. after about 200 yards or so of driving the motor boggs down.....it will stay idling but if I floor it, it will die.....if I turn it off and wait a few minutes I can turn it back on and go like hell for another couple hundred yards.... I thought the pilot might be worn out(I have it nearly closed now)......maybe the choke plunger isn't sealing or the Bowl isn't filling quick enough.....any suggestions would be appreciated.
