I love my Staun deflators ... only five minutes to deflate all four of my 33 inch tires ... faster than the ARB style deflator. But, after a year, I bumped up to 35x12.5 tires (now seven minutes to deflate) and decided to lower the tire pressure to get more sidewall deflection out of the E rated KM3s.
Messed with the deflators forever to get them dialed in to 14 psi. They seemed unusually sensitive. The first use on the trail yielded one tire at 12.5 psi, one at 16 psi, and the other two at 14psi. Damn, that's not good. Well, it turns out that the deflators get dirty on the inside ... probably some of the rubber "dust" from the inside of the tire combined with moisture. When you rotate the knob to change the pressure setting, that realigns the internal components and realigns the gummed up portions.
I disassembled the deflators and cleaned off the gunk. Reassembled them and they were as easy to reset as if they were new. Approximately three turns inward of the cap and they were close to 14 psi.
Here is what one looks like after disassembly ... no worries on the spring flying out when disassembling since it's not under compression when the cap comes off. Notice the gunk on the plunger unit ... there's some inside the bore also.
Here's what it looks like after an application of denatured alcohol ...
