Hot Start Issue Choke stuck?

What exactly is the heat stove. I ordered a copy of the Haynes manual.
I just sold an old C20 Chevy pickup I had but the carburetor was a random replacement with no factory choke. I rebuilt it but there's a lot more going on with this duster choke setup.
You may also want to check your float height, i set mine from 1/4 inch recommenced height by my 1971 Motor’s Repair Manual to 7/32 to improve the hot start characteristics in the near 90 degree weather last summer, not that that’s (unfortunately) really a problem for me now in our balmy 31 degree mountain weather today... cabin fever started early this season...
