NT Carb (old style), anyone have pics of it apart?

I took mine apart today because the bike wouldn't run, just to find the float itself full of fuel (so it probably wasn't floating), and the copper jet just sitting in the bottom of the bowl, not threaded into carb housing. Now it won't start to thread, as if the threads in the housing are sheared... This can't be right.

Thanks. I need a new one, unfortunately.
