Hi every body, I have three cns carbs the new generation these really suck they all have something wrong with them, but the last one I tried I have no power and gas pours out of the tube on the bottom of the bowl, what causes that.And it seems weird when you turn the mixture screws that if you turn one in you have to turn the other one in the old carb if you turned one of the mixture screws in the other you would have to turn out. It's not running rich I check the spark plug and it's white to lean. I have four other bike with the original cns carb those work perfect. thank for the help.
