RE: MC4000 throttle-cut mix?
In menu 1 "adjustments" go into controls and scroll through to find Throttle. If you scroll through the function list you will find "Fixed Value". Now assuming that the maximum throttle position = 100%, and shut down -100%, set the value in the bottom right hand field to -100%. In the bottom left hand field you can set the fixed value to work on any function switch, or software switch you like. When you move the switch to the "cut" position, you should see an *. If not you should press the "R" button to reverse the function. That's it.
Have fun,
