My mower would start after I took it on a trip by trailer. After verifying the battery and solenoid were not the problem, I opened up the starter cover to find that this plastic gear was wedged into the flywheel and missing most of its teeth. I removed the starter and got the gear to retract. I hooked it back up to the wires and turned the key, and the starter turned. So, is it easy to get replacement gears for this starter or should I replace the whole thing. The local shop had nothing in stock but said this should be the right part: https://a.co/d/0cCb0Wzh (PN 435320) I included a pic of the engine tag if that helps. Motor is a Briggs & Stratton 28M707.
