Briggs & Stratton started out making cars. They looked like wooden go-karts. It was start of the company that went on to be the small engine manufacturer for American lawn mowers through the 20th Century. The Briggs & Stratton engines were used in all sorts of other products. Washing machines, generators, water pumps, power washers, and the like. They got repurposed by dads in go-karts and mini-bikes. You used to see them everywhere. Every kid that became a engine mechanic had a story of tearing one of them apart.
Here's the little car that started it all. The narrator goes over the details pretty well.
Briggs & Stratton declared bankruptcy this week.
