So I have quite a bit of experience maintaining, and cleaning my Microns (well all my iwatas), but one thing I've never disassembled was my air valves. I've removed them from the body's, but never actually broke them down to get to the plunger spring. And take out the trigger plunger on top of the air valve. Well that was until today, and OMG what a little pain in the ass to get back in. I thought I was going to go crazy trying to get that back in.
