Hood Release Cable - Volvo 240

Nice weather has finally arrived , and I have replaced the hood release cable on my 1990 240 wagon (with air bags.) (I got the new cable from Swedish Engineering, and it's fine.) Here's my question: I can now open the hood by pulling on the red hood release lever. This releases the hood lock. But if I then push forward on the red lever, the hood lock does not get reset. I am beginning to think that there should be a spring in the hood lock assembly. (When I move the hood lock by hand, it will stay in either the open or closed positon, There seems to be no spring.) Should there be a spring? If not, what adjsutment do I need to make? Thanks. To reply directly to me, replace all 'z' with 'a' in email address.
