I've set up some pretty old 3009s, and every one had adjustable counterweights . . . I agree with Corby in that something must be modified or missing.
Try going to www.vinylengine.com and downloading a 3009 manual; from there you should be able to figure out what's going on. They work great with fairly lightweight MM cartridges BTW.
