Default Regulator hissing from small hole?

After a ton of drama getting my all-used kegging setup, I finally got my tank filled and attached this micromatic regular. I turn the bottle on, set the secondary to 10psi and then closed off the output ball valve and gas just continuously hisses out of this little 1/8" hole in the front of the regulator. I've looked at some pics and all regs have this hole, but what's going on exactly?

Sounds like the diaphragm (sp?) may be working improperly. I had a similar problem. I disconnected everything and took the regulator apart, reseated things, and then re-assembled. Now it works like a champ. Certainly worth a shot before buying a new one.

Ok, I opened the front housing. Now, I see the diaphragm and it has a small hole in the center of it, maybe about 1/16"and it looks like that little needle valve made the hole. Is there supposed to be any holes in the diaphragm or what? I bought it on ebay so anything is possible.

I had a similar problem when adjusting my regulator. The diaphragm got stuck and I was getting air hissing through a small hole. I didn't take it all apart, but after adjusting it back and forth a few times it eventually unstuck itself and has worked fine since then.

I took this damn thing apart and reassembled like 15 times and nothing stops it. I tried putting a little keg lube on the diaphragm where it seals to the housing. Nothing. There doesn't appear to be any pinholes in it, exept for the one in the center which I've come to find is supposed to be there.
