Another question on that KE-3; Does it need a washer or lockwasher underneath the flywheel nut.
There is no parts diagram for this model in the old service manual but it speaks of torquing the FW nut, then removing it and inserting a lockwasher and then
retorquing it. Sounds simple enough but that comment is a general one in the magneto section and i can’t link it to any particular model. When I took it apart there wasn”t one, but thats not always the answer.
