Comment on Does anyone have experience with these posts in corny kegs?

I have fixed up several different kinds of kegs over the years and whilst I can’t say for certain I have seen these posts (need more pictures to better ascertain) I would be surprised if they are limiting the flow of CO2 into the keg. I do find that sometimes these kinds of post poppets (where they are held in place in the keg post by 3 feet) can be stiffer than the universal kind (which comprise of just the poppet and a spring and aren’t held in place by anything) which can require some more fiddly placement of the quick disconnects. A cheaper fix for the posts would be to swap out the poppets for the universal kind (which retail around $2 USD as opposed to new posts which are more in the $15-$20 range USD).
When you say you have tried everything else, can you describe your carbonating process and the things you have tried?

It’s so interesting, the poppets don’t come out like normal ones with the springs (though I could probably force them out). I just bought new ones, entirely, so we’ll see if those do the trick.
I have replaced the pressure regulator, checked the lines and the attachments for leaks. I still get some pressure in the keg but the beer is severely under-carbonated. This has happened on numerous beers.
I have tried setting to the correct carb pressure and leaving it for 2 weeks, force carbing via the shaking method and the 3-2-1 method where you set the carbonation at triple, drop it to double and then to serving carbonation over three days and I’ve had these issues with all of them.
I don’t quickly run out of CO2 (which I figure I would if there was a leak and this happens on both of my kegs (which both have these types of posts).
My next step if the posts don’t fix it will to be trying a diffusion stone but I feel like I shouldn’t have to.

To get the poppets out just takes a bit of force. I usually use a screwdriver from on top to direct the force and hit it gently with a mallet. The poppet comes right out.
Out of interest what temperature is the beer at? Also is this keg the only one you have trouble with? i.e. are you able to carb other beers fine in a different keg?
Regardless, changing the keg posts will probably do the trick.

Ok, good to know. Thank you.
The beer is at 38F and I have this problem with my other keg that has the same posts. No pressure leaks at all and pre-carbonated, store-bought sixtels pour fine.
Forgot to mention but there’s almost no pour pressure, as well, despite the CO2 being near 15 psi, lines being open and there being the sound of air escaping when I burp the keg.

Yeah that sounds a lot like a clogged dip tube or poppet. My bet is on the poppet. You can clear a blockage fairly easily (at the downside of stirring up all the trub at the bottom of the keg) by switching the quick disconnects on your gas line to be liquid quick connects and blasting some CO2 down the liquid dip tube.
