Ok guys I picked up a couple fourtraxs the other day both tore down to frame but got almost every part exept a couple one had a fresh engine rebuild just needs to be installed an the other they said was "locked up" I got to messing with it and put a workig starter on it and it’ll spin it over fine but the kick start don’t work every kick it’ll kick over one then the engine will start making a whining down sound and if I kick it when it’s making that sound it won’t catch but after it stops making that sound it’ll kick over again I read it could be the one way bearing but which one and where is it located or does anyone else have any idea what it could be
