Secondary check ball missing?

I love the Holley and find them very tunable,If it were me I would rebuild that 3310 sounds like the past owner did knot know what he was doing,and yes some carbs have no ball gives a faster opening.In the kit it will have a new ball so install it and install the lightest spring you can get and go from there.There are spring kits with different opening rates.With no spring in there it will bog big time.
