Could be an issue with over carbing, serving method or some such.
What temp are your kegs at? Serving pressure? What dinension and lenght are your beer lines?
Edit: nvm saw now you dispens from a plastic barrel.

Valid point on serve temp.

if it's too fizzy, dispense ito a large jug and pour from that into your glass. Don't get too hung up on perfect carbing on your first brew.
