I think I found the problem to the leak in my new keg. The posts on the keg were reversed. The gas post was on the beer side and the beer post was on the gas side. The female disconnects were difficult to get onto the posts so, I should have figured something was wrong.
I just read read where there is a difference in the female disconnects and compared the new keg to the old keg. Sure enough the disconnects were reversed.
When I corrected this error, the disconnects went on smoothly and there was no leak... imagine that! The beer still doesn't taste great but, it's drinkable. I'm glad I didn't pitch it, though I was really tempted. I thought for sure it was infected or something. I read so many posts on another web site about being patient with a suspected bad batch of beer. I think the bite was from over carbonation.
