No that is some Emission type valvey thingy you should be able to leave it connected to the manifold if thats where it came from otherwise just block off/redirect any hoses going to it and connect the wire to the connection on the back of weber or not. I noticed the weber still had the Auto choke stuff on it but i would ditch that at some point after rego. You have to block off one of the holes when you remove it but think it will appear when you remove the above but its only a small hole. Your right it does have a manual choke but Who uses them there a pain in the butt in my experience.
