I bought from Amazon a 32mm carb for my 200cc Zongshen engine. I've got most of it figured out, but one question lingers. In the first picture you see a hose from the bottom of the float bowl to the opposite side of the carb near the throttle. (Ignore the extra length as I don't want to cut things until I'm sure where they go.) In the second picture you see a nipple just like in the first picture but on the opposite side. I haven't been able to discover its purpose. Should it be connected to something, covered or just left as is?
