Check the easy and obvious first. The Tange uses caged bearings, if one or both are installed upside down you get the problem you described. Both sets of caged should have the "open" side facing the fork crown. If that's not the issue, try using loose bearings (make sure they are the correct size), sometimes you can get away with it.
