RE: YS 110 FZ Vent and Fuel Hook-up
The Drive washer is the one I am holding not the thrust washer.Heres the deal I am installing a prop on the engine.The prop slides all the way back to the drive washer.I install the 1st lock nut.When I try to tighten the nut but the crank turning prevents the nut from tightening. I cannot tighten the nut until I hold the drive washer from turning.On my two strokes engine I often take out the glow plud and install a piston stop tool that prevent the engine from turning over as i tighten the prop nut
