I had a keg I force carbed an just about emptied. I made the pumpkin ale for a party and it was great. Long story short the keg came up to room temp but had serving pressure on it. I got a blichmann beer gun and was excited to use it I bottled it at room temp but beer seemed on the flatter side , does the beer gun work that well? Or does the force carbed beer get flatter when warm? There are no leaks in the system and beer foamed in the neck
