Wandered to the basement and checked. Secondaries should be closed as tight as a tick and the butterflies do have tapered edges so must be installed so the tapered edge seals to the bore of the carb. I've had grief in the past on 4 bbl carbs where the secondaries did not quite close--you can't get a good idle or throttle response.
