My 14 year old is extremely mechanically inclined. He's spent the last few years teaching himself how to repair and rebuild small engines -- lawnmowers, weedeaters, etc. He's the go-to guy for seasonal maintenance and small repairs for all of our local family members.
My partner and I are small business owners, so we understand the basic needs and local legalities for him to set up a teen business. He's thinking of offering seasonal maintenance at first, like filters and spark plug changes, and then branching out to repairs. I have liability concerns -- the kid can't afford to replace a fancy beast of a mower if things go awry. Spouse thinks that's silly since there are many people running this hustle out of their garages every summer.
So, has anyone done small engine repair as a side hustle? Any tips and advice for a kid wanting to do this for pocket money?
