Is it possible to change the needle valve on a Solex carb without taking the whole thing out? I ask cos I need to change mine, and I don't trust myself to take the whole carb out, cos I probably wouldn't be able to put it back - but the Haynes manual says I have to.

Is it feasable to take the top half off without removing all of it?

you'll do a much better job if it's out. It's really not that difficult but it's important to keep things nice and clean when working on carbs so you'd be best doing it away from the engine where there's lots of crap to drop in the carb!
