They came with my kegs from Kegco but I think they're limiting the beer's CO2 intake. I'm going to swap them out for traditional ones today to see if they make a difference.
I have been plagued by poor carbonation and I have tried everything else.

I was thinking the same. It's a hazy IPA and I had a floating dip tube on there which fell off after kegging and carbing, so I put the regular dip tube in.
I'm wondering if there's not even enough carbonation to force the beer up through the dip tube but I will see.
You basically don't need any real pressure in order to force liquid out of the keg it's just that if the pressure in the headspace is lower than the equilibrium pressure of the carbonation, then gas will come out of solution in the beer as it pours and it will go flat. If you pull the manual pressure relief and hear gas escaping then the beer should absolutely pour which again seems to suggest that something on the liquid side is clogged. Did you dry hop the beer in the keg?
Ok, very good to know. No dry-hopping in the keg and I transferred it to a secondary and then the keg, which removed the majority of the sediment (though it is a hazy IPA).
I'm interested to see if the dip tube is clogged as well, though.
Hmm. I would personally try blasting some CO~2~ through the liquid post to clear out any blockages.
For what it's worth, here's what the old post looked like.
I put the new post on and the beer immediately went up the line out. I don't think there was a clog at all. Going to leave it for a couple days to see if it makes the difference.
I don't notice anything super out of the ordinary. The poppet does appear to be more depressed than usual (they usually sit flush with the top of the post) but if anything I would think that it would be more likely to flow normally in this state (rather than not pour properly). I'm glad the new post seems to be working at least!
Yeah, we'll see if that does the trick. Thanks again!
Yeah, not removing the dip tube entirely?
Also, I would assume with a slow leak that I would find myself running out of CO2 pretty quickly, right?
I mean you could remove the dip tube but then you are opening up the beer to oxygen and potential contamination. Blasting gas through the liquid post can help clear clogs without opening up the keg. You can check for leaks by spraying the posts and the lid with either starsan or just soapy water.
Yeah, I was worried about contamination, too. I'll give your method a try. Thanks for all the advice!
Last note, here they are (liquid posts but they're identical in size to the gas ones) side by side.
The distance from where the lock on to the top of the post looks the same, so we'll see if this does the trick.
