Kohler 25 command pro idles just fine and dies when throttle is slightly increased

The machine was working fine while mowing leaves and then just died.  Ever since then, it will idle and nothing else.  I have rebuilt the carb a few times with no change in the engine performance.  Bowl is full of fuel when I remove the solenoid, so I don't think it is pump/lines/etc.  What should I look at next?
 
Thanks.

    Try spraying carb cleaner down the throat of the carb when opening the throttle.
     
    We're checking to see of it's a fueling issue..

    Well, I figured it out.  Turns out the fuel shutoff solenoid only cuts of fuel to the high speed jet and not also the idle jet.  I tested the solenoid on the bench and nothing.  I then pulled the plunger and spring from it (to disable it) and reinstalled it.  Machine runs great.  New solenoid ordered.
