O.K., dumb question (expect it, I'm from Oklahoma). How many of you carburetted guys use a PCV valve-in non-emmissions states? If so, why? If not, Why not and what do you do with the PCV port on your carb? Do you just use breathers for both valve covers? How does this effect performance and manifold vacuum-both with and without? Remember to talk slow. Thanks.

i use it for two reasons. 1) it keeps the crankcase ventilated, and 2) i could use a breather, but unlike a breather, i don't get dirty engine vapors on the valve covers and engine compartment.

It also helps the rings seal better. And helps to remove moisture that builds up in the crankcase from short trips.
