kegs won't carb

[bent]

I kegged a Mirror Pond clone(25 gals.) and it won't carbonate. I usually force carb at 60 psi overnight for the first keg so I can drink it soon but this didn't work for me this time. It's been at 60 psi for 2 days and still not carbonating. I have no leaks in my system. Temp is at about 38 degs. as usual. Any ideas?

I also filled a sanke keg that has been at 20 psi for 2 weeks with no luck.

That just doesn't seem possible. I'm scratching my head.

When you turn the pressure gauge up, do you hear gas going into the keg? When you pull the pressure relief valve, do you get a big "hiss" of co2 escaping?

oh ya, plenty of gas going to it and plenty leaving if I vent. F'n weird.
