That might be fine for string trimmers but when it comes to hedgers and chainsaws that there are limits that if exceeded will shake things apart on hedger or exceed maximum chain speed allowed. On top of that many trimmers, hedgers, and chainsaws are now coming with limited coils where if you exceed the max design speed things just get crappy; unless, you across an unit that is dieseling like I did back in my Spring here.
The coil was limited to 9300 but the hedger was exceeding 12000 without a single spark. I figured it out when the tach was showing zero rpms at wide open.
There a lot times that I got to set the idle rpms below the clutch engagement speed even though it can much run higher at the sweet spot.
