Exhalve valve not working (4A1)
Just got a 4A1 delivered. When trying it on, it makes a negative pressure seal if i cover the intake, but it also exhales from the intake instead of through the exhale/diaphragm while also fogging up the glass. Might it be beucase its dusty or could it be something else?
