Geoff , not trying to get you confused on the photo you pasted you see another tube coming out of the cover plate where your choke insulated tube is rusted off .That other tube (U shaped ) basically draws in air to be heated over the exhaust manifold and as hot air rises fallows its way up the insulated choke tube to the choke assembly to warm up the bi metallic curled strip under the choke cover which in turn warps larger pushing your choke plate open .
