I was out riding my loncin hunter 250 yesterday when i thought i'd go through a mud hole but it did not liie that and after that it started running bad but still ran all the way home, i shut it off for the night and when i was going to start it this morning it would not fire unless i had full throttle and even then it ran bad with a lot of white smoke. Does anybody have any idea if it can be fixed or if i might as well buy a new quad
