Dave,

Is there anyway to add an airbleed to the NC carb body? The regulator does very little for the idle mixture, and quite frankly the idle sucks depending on weather conditions. I know the hole in the butterfly can be enlarged, but that is hit or miss thing that can cost you a new butterfly if over done.

Thanks
Jeff

Drilling the airbleed to 1/8" is the only thing you can do.

Thanks, I will try that then. Why on earth did YS leave off idle mixture adjustments. That is just plain idiotic!!

I agree, it was not one of YS's better thoughts. The NC is 10+ years old, maybe they've learned something, as all the engines now have adjustable airbleed.
