Jun 17, 2020 · I didn’t know McCulloch built go-karts, I know they were a big chainsaw motor supplier. My old man had an old McCulloch chainsaw, we called “The Widowmaker”. We tried to get it for a go-kart ourselves, but the old man refused. Twin engine karts like this had a short history. Small engines hadn’t yet got powerful enough, so 2 were needed.
