so here's my carbing octopus...well, half octopus I guess.
I got it complete, hooked to the CO2 bottle and listened for leaks.  Didn't hear any so I went out to the garage and dunked all of it except the wye connection to the regulator in my bucket of starsan.  I checked it after 5 minutes.  The top of the bucket was like glass and there were no bubbles.
I then sprayed the wye connector to regulator connection with starsan and saw no bubbles and then sprayed both of the check valve to wye connector connections and saw no bubbles.  I then sprayed the flare fitting to check valve connections and once again saw no bubbles.
I then changed the faulty post/poppet on my keg and hooked everything up.  I listened very closely and heard nothing.  I also wiggled all the connections and heard nothing.
I think I'm good to go!
now I have 3 pin lock kegs and one 2 liter bottle with carbonator cap all carbonating at 11psi!
