      brian,
      for my enlightenment, what kind of carb is this and what kind of motor is it. Most 2-cycle kart engines won’t idle. And if you set the carb to idle, more than likely you’re running too rich to run on the track. Way back, I did use a piece of a match book cover under the butterfly stop to keep the plate partially open and the engine idling. On the first blip of the throttle, the match book cover was gone.

      My bad… I’m running a cr125, with a Keihin PWM. I believe my kart mechanic, set it up to run rich so I can run the top end longer between rebuilds.  I don’t plan to race any time soon,  so getting it to idle would be a great help.

      What pilot and needle are you using? If you set the PWM to idle, you can easily cure the issues you are describing with minor changes.

      Idle is around 20-24 clicks out, pilot 55-58, CCJ, CGJ, CGK needle P4 or P5.
