My Carling Keg is Flat? Help

[dafish]

New to this so I hope someone can help...
I setup my first keg of carling on saturday and poured around 20 pints that night at a psi of around 6 (not sure if this is correct?) the pints seemed to be a little foamy.....
However that night the gas bottle was turned off and the preasure overnight had all been lost, now when I pour the pint I get a comnpletly flat one.
Can I recover this? I have turned on the pressure up to 35psi and gave the barrel a shake and left it like that overnight. As I have read I can force carbonate the larger easy enough again.

Is this correct and if so how long will this take at this pressure?

Also I have a knob at the bottom of my beer pump on the line, is this the flow restricter?

Thanks in Advance.

There is no formula for recarbonating a keg. You can take your chances and rolling the keg will help but there is simply no way to know how much or little gas you are imparting into the beer. Once you have consumed this keg, target 38 degrees liquid and 14 PSIG on the next one. Research other posts on this site as to correct set up. No idea what your are referring to as to the knob on the beer pump[?]
