My original carb had strange issue's when I first got the car and it took awhile to find out someone had drilled two holes from the outside of the carb base to under the butterflies, basically for the same reason but UNFILTERED air?
If those holes were truly to the underside of the butterflies, then yeah, that's a no. But if they were these kind of holes (start at linked post and keep scrolling down for documentation), they were put there at the factory for a good reason, and they were supposed to be there.
