Just that when you rev it where you want to it either wide open or idle on both the fs an Km 90 just not felling they are what I want an what like :thumbdown::frown:
That's the way it's designed to run, (WIDE OPEN) The recommendation is to run a trimmer or an edger is full throttle because running it too slowly will contribute to carbon buildup in the exhaust port, piston rings, muffler, and contribute to fouling the spark plug. You can ruin an engine running it at a low speed.
