The soda in the glass still was flat, but the head was smaller.

Any other ideas?

A few hours after the above try I changed out the picnic tap on the line for my other one and was able to get it to hold the soda in the line at 10 PSI, but at 30 PSI the soda would just flow on out. Not that that solved anything. I'm still getting a flat soda with all a big head.

Going to try and degas in the keg a bit. I'm hoping I just over carbonated it.

Hmmm. Are you opening the tap completely and fully? The reason I ask is because sometimes people try to slow down a pour a bit, and sort of squeeze the tap. That makes it shoot out like a firehose (like pinching the end of a garden hose). This doesn't make sense.

Can you double check the connections of the black QD and then look at the post itself and the poppit? You can even take the black QD apart to see if the o-ring in there is ok.

I have only been opening the tap fully.

I took apart and checked the connections of the black QD. It looks like it is okay. It is threaded correctly, the o-rings are in good condition, and the poppet is free to move. The poppet is able to move a bit from side to site once depressed, but it makes a good seal once I stop pressing it down.

I have two kegs. I'm having the same problem with both kegs but they have different sodas. I'm about to dump out the ginger ale batch I was making (for some reason it has lost its bite) and try to carbonate some water. Would that prove to be a useful experiment?

I don't know. I'm at a loss. I've kegged lots of sodas, and never had an issue.

One last thing, The tubing I was sold is vinyl tubing. From what I have read vinyl tubing will offer less resistance and therefor back pressure. Do you think that could be a contributing factor?

I don't know. I've been using two kinds- the beverage line from the LHBS, and the semi-rigid line from McMaster-Carr- with good results. If you're up to 40' of 3/16", though, that doesn't seem like the problem.

sounds good. Thanks for all the help.
