1959 AMC 327 with Holley Carb.

A recently acquired '57 Hudson Hornet Hollywood has a Holley carburetor on it(we believe from a '59 AMC), perhaps a 4160 I cannot confirm yet as no tag exists. But in schematic for the carburetor that show the Climatizer assembly, there is a small black plastic rotating piece between the climatizer and the carburetor called "Float Spring." What is the purpose of this? I've had difficulty setting the choke plate to initially close. This plastic piece is just sitting there and moves up and down maybe 45-60 degrees but I do not know what it is supposed to do and there really is no ready access to the piece.

Thanks.

'bump' or a picture of you pointing to the part you are talking about?
Maybe the climatizer is what we call the choke housing now?

Can't readily see how to post a pic without uploading it to a website for sharing.

For those who don't know, in '57 the AMC 327 would have come from the factory with a Carter WCFB, with either #2593S or #2593SA.  Since the Hornet in question has a Holley, it likely would be from a '58-up.  Is there a Holley model number stamped into the carb base?

I haven't found a carburetor number yet. There is no standard metal tag attached. We know the engine/carburetor was replaced on the car years ago but that's all we know. The owner passed away and we received no maintenance records or history of the car as such. We've been trying to adjust the choke climatizer to close the choke for startup and I've been able to get it closed when cold to within perhaps 1/16" which has made it warm up significantly sooner. But with this unusual black plastic imbedded down in the components, I'm wasn't able to determine what it's significance is or whether it is actually working. Having no carburetor ID tag and not knowing what AMC car it came off of, I just cannot produce any actual diagrams or schematics.
