This link has tech specs for Solex carbs, but if you have a Haynes you've probably already seen this...
I hope the above is of some use. I just typed "peugeot 205 xs carbs" into google. If you know what make the carbs are, type that into google see what comes back. When i had mine my dad and i had many weekends of "fun" tinkering with it!!
