Crappy pic but is this what you are looking for ?
no, that is of the enrichment valve it self. you see the small tit that doesnt have a hose hooked to it? if you look in my pic, that metal pipe comes out of the right side of the carb and is attached to a bracket that is bolted down with the carb and then gets attached to the enrichment valve with a rubber hose.
if you look carefully at the goose neck in my pic., there is a clamp that holds the AIR hose down that comes out of the pump and into the left side diverter valve.
