air pockets in beer line?

[pandemonium]

so i loaned my kegerator to a friend and now it is not acting right. on every first pour it shoots air out then pours fine until the next pour. when he first tapped the keg and for like a week it was pouring great?? any ideas?
thanks

Maybe the thermostat was adjusted and the beer is too warm. If the beer is too warm behind the faucet (in the tower), it will cause the CO2 to breakout from the beer and build a pocket of foam.

i checked the temp and it was fine, i checked all the basic things i could think of but i did notice that the coupler does not seem to have a good connection to the keg as i can simply turn it left and unhook it without releasing the lock handle if you can understand what i mean? maybe this is normal i have never messed with it but maybe it is a bad keg? but i wouldn't think air would get in there just leak out if it was a bad connection?

no suggestions?

The bottom seal washer on the coupler may be defective or worn out. Inspect and replace if required. What is your beer temperature / PSIG to keg?

not sure on the temp but it tasted plenty cold last time i was over there, i am not there to measure it right now
