right, decided to give my tank a good clean (bits of rust around the the tap, lock etc) with wd 40, however when im going to put it back on, i have a problem.
i know where the fuel line goes onto, but what about vacuum hose?
there is a place to connect it above the fuel hose, or at a 90 degree angle clockwise to it facing down?
haynes says the one above the fuel line, however that is for an nc30

Its the one pointing directly downwards on the 24 :)

cheers, whats the other for then, above the fuel line

I'm not actually sure, but i think it might just be a breather?? Theres nothing attatched to mine either.

It's what lets the diaphragm go back 'in' to block the fuel off when there is no vaccumn anymore.
