I was cutting an overgrown lawn with my snapper and hit a scooter handle bar that stopped my mower. I tried to start it back up but to no avail. I figuered it was the flywheel key that was sheared. My dealer is going to fix it on tuesday I believe. My question is if I can fix this on my own or should I let the dealer put the new key on. I have never replaced a flywheel key especially on a kawasaki. What should I do?
