so i was sick and tired of messing with my holley 94 and picked up a new stromberg, the made in england kind. while reading the info that came in the box i read this, WARNING! Do not use this carburetor where a Positive Crankcase Ventilation (PCV) device of any type will be used. i am running a pcv on my flathead, single carb,stock intake. why would it be a bad thing to run a pcv? should i go back to a road draft tube? thanks.
