John,
Here's a Huret Jubilee RD parts breakdown:
Short arm: >http://www.velo-pages.com/main.php?g2_itemId=2559&g2_imageViewsIndex=1
Long arm: >http://www.velo-pages.com/main.php?g2_itemId=2562&g2_imageViewsIndex=1
The Jubilee RDs were made for either proprietary Huret dropouts or Campy style. They don't interchange. This was kicked around a while back, check the archives.
Here's a link showing the difference in the rear stop for the short arm versions:

Some suggestions:
1. Throughly clean the derailleur with your favorite solvent/cleaner.
2. Remove the lower jockey wheel and loosen the nuts a little so that you can flush out all of the old crud rather than completely disassembling it. It's full of small ball bearings. This will also give you a feel for adjusting the upper jockey wheel.
3. Loosen the screw that holds the cage onto the body enough to get to the upper wheel. Loosen and flush the same as the bottom one.
4. Readjust and reassemble.
Good luck.
NOTE: Jubilee derailleurs were far from robust especially the long arms RDs. Huret long arm RDs were designed to work with fairly close ratio freewheels and wide spaced chainrings such as a half step pair with a granny triple.
