It is a 'poppet valve', Hdhikaru....
With the choke closed, atmospheric pressure opens the valve when the motor is kicked, but prevents reversion into the air cleaner.
Previous models had simple holes.
A solid disc would draw a flood of fuel.

Not adjustable, just a spring loaded disc against the atmosphere....Robbie Knight Amca #2736Comment

Sorry for a late reply, Shin,..Originally posted by hdhikaru View Post
The assembly is peened to retain the valve with spring upon the choke disc, and usually only needs cleaning for inspection.
Its function is dubious enough without the confusion of adjustment; It is an example of classic over-engineering for a conjured benefit,
Just a simple hole (of appropriate size) worked for decades.
