I want to start this off by saying I am not new at kegging. I have kegged and force carbonated my annual limit of home brewed beer for a while now with no issues. But this issue has me stumped.

I brewed a 10-gallon batch of a milk stout a while back. I screwed up and I forgot to add the lactose to the boil so I just split the addition and boiled some water to sanitize it and then dumped the whole mess into each keg. I racked the beer into the keg and then purged with co2 and shook it a bit to mix it all up. I put the kegs on co2 to pressurize them. Once they were carbonated the first keg went into the kegerator. I served it at 12psi, like all my beer, and it was amazing. Perfect head wonderful flavor.

The second beer went into my cold conditioning and storage chamber. I have up to 6 kegs in here all staying at 36 degrees and hooked up to co2 at 12psi. When the first keg kicked I dropped the replacement keg into the slot in the kegerator. It was nice and cold and supposedly carbonated.

I poured a pint to clear up anything that settled in the bottom and make sure it was pouring nice.

No carbonation. Now, there was some, but very little. Perhaps 1.8 volumes. I thought that was wierd but perhaps my regulator gauges were wrong. So I left it hooked up for another 10 days or so at serving pressure. By then it should have been carbonated. No change. So I hooked it up to ~50psi and left it for a while. I got busy with work and totally forgot about it for 3.5 days. WHoops! In this case there as a slight change. But still not pouring a head.

Some troubleshooting facts: I poured the keg with 12psi and with 50psi. There is a noticable difference in speed. the 50 psi would fill the glass in a couple seconds. There should be nothing but foam in the glass with either pressure at this point but I still have to work to get ANY foam, let alone a good pour.

The beer comes out easily with no noticable obstructions. Also, the co2 obviously goes into the keg.

This beer is from the SAME batch. There is no change in anything other than different kegs. Where did I go wrong? This keg has been used before by me and I have had no issues.
 
My guess would be either a leak, or a clogged gas port. I lean toward the leak.
 
I keep a bottle of starsan solution near the keg fridge and spray all the fittings and the lid to see if it is sealed after putting it on gas. This sounds like you have a slow leak on one of the fittings of that keg. Maybe a slightly worn O ring on one of the posts or the lid.

** Edit ** This is assuming you are using cornies. There are a lot of parts that could have a slow leak. I would put 30 PSI on it and then pull the QDs off and spray the in and out post and check for leaks. Then re-connect the QDs and spray them and check for leaks. I have had a couple kegs where the poppits were worn and didn't seal properly.
 
Well, I don't have the solution to the problem, but the problem is solved. It wasn't a leak issue or a plugged gas port issue. As I could definitely put gas into the keg and when I pressurized it to different pressures it poured at different speeds. I left it on high pressure for the last week, but disconnected from the regulator, and it had lots of pressure and was fully carbonated.

So while I can't help anyone that might have this problem I CAN enjoy a pint. Okay, I have to admit, I already enjoyed 2!

Thanks for trying guys.
 
What temp do you serve at? Could it be that once the keg warmed up the existing gas in the keg was warm/volatile enough to produce a good head?
