Vacuum gauge readings help

A little help from you more experience fellows would be apprecaited. I had a vacuum guage on the PCV port of my carb, The needle was jumping rapdily between 19 & 21 inches and doing so consistantly. Adjusting the idle screws has no effect on this. Is this indicating some sort of valve problem?
