so ive been searching the forums and been getting a lot of mixed answers so i thought i would try and ask the question. i have 2 kegs in my kegerator, the ambient is 29 degrees havent checked keg temp. my beer lines came from midwest so whatever their lines are is what i got 4 foot i guess not sure. both kegs are at 8 psi and i get 80% foam in every glass i pour. what am i doing wrong i cant figure it out
