And as for fully adjustable carbs, just bought a new Husqvarna 223L trimmer and a new Echo PE266 extended hedge trimmer. They both have fully adjustable carbs--low, high, and idle.
They are not truly fully adjustable they let you adjust to a point Like old models you really could crank them up
My brother has a new 223L and He ask if I could crank it and you cant they are restricted to where it only lets you turn them very little He traded it back in for bigger one. The 223L was a turd in tall grass
