1990 ir185wjd when I cut off the air at the end of the hose, it pops the service air button.


i have replaced the rubber diaphragm at the intake on the pump.

The idle governor is working properly.

The pressure gauge is registering correctly.

I replaced the service air button which is also the regulator on this model(IR calls it a 2-way valve).

The motor runs fine and pump is producing good pressure, but if I turn the valve off at the end of the hose it pops the service air button out of service.

However, I can leave the second air valve cracked just a little bit and it doesn't pop 'off' but I lose a little pressure from the side I'm using.

I can't seem to find anyone around here with an answer.

Thanks from Kimberly Idaho.
