I am having a problem with the pull start on my lawn mower. When it is running it is rubbing on the plastic ears that engage the flywheel. I have replaced the ears and the assembly once and it stripped out the ears in 20 minutes. Nothing looks warped on the flywheel and I don't want to buy another assembly as I am sure it will be ruined right away. This is the one disadvantage to an early spring in Wisconsin. Normally I would have another month to deal with this.
