Depending where you live, it can be really hard to find ethonal free gas. As an added bonus, carburators hate having ethonal sit in them. They’ll develop a varnish. Carbs also don’t like sitting partially dry and getting all the fuel out of them is a massive pain. Yay lawn equipment.
My electric chainsaws and weed whacker always start. Eventually our lawn tractor will kick the bucket and I’ll either convert it to electric or buy one.
