I'm gonna add a little tip here for removing the jets with the carb in place:
The jets are soft brass, and the slot for the screwdriver runs across the hole in the jet, and they can stick, and you need to get the screwdriver into a narrow channel. I'd suggest making sure you have a small screwdriver that is in good condition (a clean edge). I bought one that is also narrow (it doesn't have the flare on the end that most do). I only use it for replacing jets. My girlfriend picked it up one day to undo a screw on a door or something - that was the day she learned the rules about my tools
It might seem like a small thing, but if you're going top poke around in the carb in situ, you don't want to bodgy anything up, otherwise you'll be removing it anyway to repair the stuff you mashed outta shape.
Aaaand ... as others have said before, swap the carb-bowl screws with some SS allen key screws (and put some anti-seize on them) while you're there. It makes life easier later.
