it doesnt hook to the cable.
it sits in a lil hole in the slide. the cable hooks to the slide.
the slide pulls needle up with it.
the needle should have a clip on it, middle slot standard.
theres usually washer sort of thing above the needle, with a slot to clear the cable. otherwise a clip of some sort. otherwise its not terribly important anyway! so dont worry! just holds needle down in slide, stops it jumping around and giving rich surges.
get that? one clip ON the needle, to locate it heightwise in the slide for mixture, one washer thingy that rests on this clip, and is held down on the slide via spring, keeping needle in place!
then the spring to push slide down. then the cap.
then the lil rubber boot/silicone sealant around cable as it enters cap to stop stray "air leaks"
