while cleaning the idle valve, I notice that the adjustment knob for the aux air device was broken. I manage to find a replacement for the knob from a junk yard. Some how this has improve my 190E rough idling, though not completely cured as I still experience slight mummurs. Please explain how an aux air device (which is connected to the idle control valve) function and also how it work.
