If you can see all that stuff, the cover has been removed long ago. Three rivets had to be drilled out to remove it. If you look closely at them, you will see at least one of them has a 10mm nut under the remaining part of the rivet. Sorry, but I'm doing this from a tired, old memory. The one you're after, I seem to recall, is the one that's closest to the front of the car. Loosen that nut. That will allow you to rotate the curved adjuster for the automatic choke. I think you want to push it as far toward the rear of the car as possible to the end of its limit, then tighten the nut.
The thermostatic spring on this carburetor is so strong, it will raise cold idle speed without you having to tap the gas pedal to set the choke. Adjusting the choke will stop it from overloading causing black smoke out the tail pipe and fast idle speed will be lower and come down sooner.
