350 holley fuel rich running issue

for some reason my holley 350 is leaking fuel in the vacuum chamber behind the power valve making my car run really rich, but still pretty good.
I have a lumpy cam in it, with 107 lobe sep and 287 #50 duration with 430 valve lift.
the vacuum is at 13inch which is normal for a hot motor to have low vacuum like that, so ive got currently a 7.5 power valve.
at first I thought the power valve that was in it was faulty so I replaced it.
