A Schraeder valve wouldn't be using a Schraeder to Presta adapter in the first place!
My Presta pump doesn't depress the pin on my Presta valve either!
If I don't manually "burp" it, the air pressure won't overcome the "stickiness" of the pin.
Apparently you have a different "understanding" of air chucks. There isn't a "pin" in the
AIR CHUCK that gets depressed!
