I think I've tried everything and am still pulling what is left of my hair out.
I have had no luck carbonating beer. No matter what I do, I get flat tasting beer (IPAs) with lots of foam.

The fridge is at 38F (checked with two thermometers in a glass of water). Using 12 psi set and forget for over 3 weeks. Was originally using 5' of 3/16" beer line, then changed to 10' (based on reading up on resistance). Still flat tasting with mostly foam. Checked for leaks and found nothing.

At first I thought I was undercarbonated, then overcarbonated and now I'm just confounded.

Any ideas would be greatly appreciated.

Might be a stupid question, but do you have any way of testing your regulator gauge accuracy? If it is reading high than you would be undercarbing, but that doesn't explain the foaming unless it is the first pour that has warmed in the lines that is foaming.

Have you tried blast carbing at 30 psi for 48 hours and then dropping down to serving psi?

Was reluctant (because of fear of overcarbonating), but yep - tried that. Still same results.
No way if testing the gauges.

If you are getting a glass full of foam, then you have carbonation. The only problem is that the foam is the carbonation that has been released from your beer. Once the foam dies down, the beer will taste flat because of this loss of carbonation.

Try pouring a beer with nothing but foam and then pouring another glass right behind it. If that second glass is more beer than foam, then you have a warm tower or faucet. If the second glass is the same as the first, then you I don't know what to tell you since you lengthened your beer lines.

If you have a tower, you need to look into tower coolers so that the first glass isn't all foam.

Haven't tried that. It is about 75 - 80 in the garage now. Using a fridge with faucets. If that's the problem, is there a product or DIY (faucet cooler)?

I know you can get a project box with a fan from Radio Shack and a hose that goes up to your tower. Do some searching in this forum.

Not for a tower, but a faucet through the kegerator door.

First glass did have more foam than second. Neither was more beer than foam though. Second glass was about half and half. So that would answer the foam problem. Is this problem and the flat tasting beer related. Would pouring multiple foamy beers eventually cool down the faucet to the point where the beer-to-head ratio is normal and the carbonation is inside the beer?

vent the keg and crack the lid and scoop some beer with a sanitized glass - if its carbed then your problem is in your faucet/lines somewhere

If you're pouring foam through 10' of line, the beer is overcarbed. Also, just to be sure, you're opening the faucet all the way right? Is the foam coming out fast?
