AVS 4966 Parts

I bought a carburetor from someone who didn’t state it was missing important pieces so now I’m trying to figure out if they’re out there. I need the vacuum choke with screw and rod as well as the well as (forgive me for not knowing what it’s called) the rear secondary plate? I ha e pictures from the other AVS I have to use as reference. The carburetor number is 4966s. Any leads would be greatly appreciated.

Thanks,
Jake
