Hi I have a 1973 Honda XL350.  There is a nipple on the side of the carburetor right next to the fuel line hose, to the left close to the engine, see pic.  Does anyone know where that hose is connected to on the other end. Also there is another nipple on the engine on top behind the points, where is that hose connected to on the other end.

Thanks.
