First: Get this book -

Then, using that book, rip into the carb. It shouldn't require anything else special.
Purely out of curiosity though, which Q Jet do you actually have? There are about 20 different combos when you factor in all of the chokes/pulloff styles/flow ratings/computer controlled.
Just one thing though.......it sounds like this carb is OK. Why take it apart?
