The ‘flat disk’ valve is known as a ‘Daytona design’. The only downside of this design is the use of ‘extra’ seat gaskets to set the float level. While float level setting is covered in the Daytona directions, and millions of Zenith carburetors use ‘extra’ gaskets to set the float level, on occasion the tab on the float will not be set to touch the center of the Daytona valve. Excessive side force will result in a leaking valve, and engine flooding will likely follow. Since the valve is free of rotate the depression in the seat may appear to be the same all the way around, but that pesky side force may still be the culprit. IMO the flooding and idle problem are likely related.

In your second picture the valve in the lower right looks a lot like the accelerator pump check valve.
