    I have read reports of the CNS carb idle air screw being sealed in place for EPA requirements. I suppose it is set for a lean idle mixture. If I had one I would just increase the size of the idle jet (for gas) by buying another one or drilling out the stock size. Does anyone have any experience modifying it? How does it run without being able to adjust it?
    Since it is lean I think it may work well at high altitudes. So please relay to us the altitude where you are at along with your experience.
