Don, I had the same problem years ago with the first 200 that I owned (and which was in fact the first 'real' AB I ever had). I ended up roughening the end of the nozzle with emery cloth, which did the trick. (I was afraid removing the nickel plating would encourage corrosion, but it was never really a problem.)
The 'glue' idea didn't occur to me, but it isn't a bad one; you didn't say which one you used...but would something like clear silicone work any better?
