should i install a 6 mil vapor barrier over kraft face insulation? | |

no - definately not
you are doing the right thing by installing the kraft face insulation - leave it at that. adding the poly would double up the vapor barrier and eliminate the ability for the wall to breathe (which it can through the kraft face). try not to use poly anywhere in your home as it will trap moisture.
