Welcome to the best forum on the web from Central Texas.....jpullen
I have a new CNS carb that I have had sitting in a box now for several years, never even tried to run it, bought it and started seeing so many issues with them here on the forum I just stayed with the NT and have always had great results with them, very simple carbs that when jetted properly just plain work on these little engines.
I have seen that the new version of the CNS carb seems to be much better than the 1st generation ones like what I bought way back when, having the option to drill out that plug and have an air mixture screw is what seems to be making them so much easier to tune, You may do some digging on forum and take xseler's advice and do that mod to yours.
Best wishes on your build and happy safe riding.... keep the rubber side down my friend.
