Carburetor Question Carter WA-1

When I bought my '39 Six, I decided one of the first upgrades should be a rebuilt carb as, in the past with other vehicles, a 'new' carb has cured all sorts of ills. I researched the original type on this site and determined the correct unit should be a Carter WA-1. I submitted pictures of the unit that was on the car to the 'carb guys' and they advised it was a Chevy carb off a '56 Bel Air. I was given the option of automatic or standard choke and opted for the standard version. My woes with trying to get this car to run have been well documented on this site and I decided to procure yet another rebuilt carb to see if possibly, the first one was in some way, deficient. The carb store told me to go with the automatic choke version as that is what came with the car originally and the standard choke unit was a 'generic' Carter carb that had different porting and jets than the 'original' carb????? This makes no sense to me, but my 'carb smarts' are quite limited so I just 'did what they said'.

My question is this: there is a male threaded port coming off the auto-choke 'element housing' and I have no idea what should hook up to it. The Chevy carb was auto-choke and there were no fittings and the first rebuild manual choke had a sleeve cable (that I installed) and now this version has this, about 1/4" NPT fine thread, on the bottom of the choke housing. If anybody could send me a picture of the proper hookup procedure, I would be most grateful. Many thanks in advance.
