Swamp mix. That’s what you call a concoction of two-stroke oil and gas that’s been slopped together with no measuring tools and no regard for engine protection. Your chainsaw or string trimmer could be running on a 50:1 mix. Could be 72:1. Could be 147:1. There’s no telling.
As my friends and family will attest, I have a wide range of interests, but small-engine repair has never been a hobby of mine. Nevertheless, because I own a little property, I’ve had to own all the basic equipment necessary to maintain it, from chainsaws to lawnmowers and snowblowers to string trimmers.
