Sorry I have not been on here in a while, moving back in with the inlaws put a stop to my homebrewing. But I can't take it any more, so I started getting things back together, when I realized the screw on the regulator would not screw in and out. I bought it from Austin Homebrew about a year ago, and really have not used it in about 6 months. It does not look like it is cross threaded or anything, so I don't know what happened. No rust either. I don't have time to crop the picture, so I just put it on my website, and here's the link MattCraft.info
it's a little big but maybe someone might be able to help me out. Thanx.
I did talk to Austin Homebrew, and they have the regulator rebuild kit, but no cap or screw. And it's not on there website, you have to call and ask for it.
