hey everyone, Ive built some 2 stroke engines in the past, but im wondering if im doing This right with my husqy wr125 from 2009. On the righside of the crankshaft, the drawing only shows me the spacer/bushing then the 2 gears, and then the nut to finish it of. but the drawing is not showing a o Ring for underneath the bushing, but ive seen some wr125 engine rebuild video's where they do add one. my question is, does it originally needs to be with or without an o ring underneath the bushing, because the technical drawing isnt showing an o ring either. Thank you guys already.. Greets koen
