Random Thermoquad Carb

Hello everyone. I'm taking on a little project which involves rebuilding this Thermoquad carb in pretty bad condition. It's not a very sought after model but I'm just doing it for the practice. I'm a bit confused as to how to remove the linkages on one side of the carb. In the pic attached, I have scribbled in 4 blue arrows. 3 of them are pointing to some rectangular-looking tabs and the last arrow is near the center pointing down to a circular piece with an indent for a flathead. Do the tabs or that circular piece come out? If they don't, what gets removed? I'm trying to split up the top, middle, and bottom parts of the carb to clean each one. Thanks everyone!

You do not remove those. They are permanently bradded on.
