For years I ruined gas lawnmower and generator engines because I couldn't fix them (or would let them sit up gasoline in them.) I finally bought an electric lawn mower (corded).
I love it. The biggest problem is, people look away and wonder why I still have my "Man Card" (even DW). But hey, I was only a Diesel mechanic 2 years, I was an electrician for 20.
It can't cut high grass though and burns out the 'bridge rectifier'. That is easy to order and swap out. Cleaning a carbutator, not so much (for me.)
