fixed starter

Repaired the "new" John Deere ride-on mower. It would not start when Nicole tried. The starter was running but not engaging the flywheel. I removed the Briggs and Stratton engine cowling (which enabled the mouse removal). I was expecting broken teeth; they were fine. I poked and prodded the small gear. That seemed to fix it. It flew up the shaft on all subsequent tests. Sticky, I guess.
