I disassembled/reassembled a Briggs & Stratton in HS shop. I thought it was going to be a stupid exercise - it wasn’t. Hands-on fundamentals learning lasts a lifetime in ways you’d never expect. Had my heart in my mouth when we finally started her up - and cheered when it worked! LOL
These days doing a ring and valve job on a small engine costs more than replacing it due to the high cost of parts and labor.
No need for the < p> symbol as long as you don’t use any other HTML in your post. Just a space will separate paragraphs nicely.
Unfortunately, most HSs don’t offer shop any more. Pitiful! Raising a generation of dependents.
I have donated lawnmowers, when replacing over the years, to the high school. They use for shop class, and they also offer a mower tune-up/blade sharpening service each spring.
