Sorry... I know this is an old thread, but I was just about to post about the same problem, but with a slight twist...
I DID order the right throttle cable P/N from Richard, according to the parts catalog downloads. But it also does not have the required 90-degree thread-in elbow, just like the original poster was asking about. Even the catalog pictures do not show it.
So I was going to ask how in the world I was supposed to get the old elbow off my old cable (I ended up just snipping the old cable) and get it on the new cable, because it looks impossible. The cable ferrule is too big to slide through the elbow.
I first tried by pulling the black plastic Y-connector cover apart and unclipping the two lower cables from the white nylon connector inside, thinking that maybe I could then disconnect the upper cable from it and pull it out of the sheath... but no go. The upper cable won't unclip from the white nylon connector because the ferrule was crimped on after passing through the connector's center hole.
I guess I'll have to cut the ferrule off, but the elbow on, and crimp a new ferrule on. Doesn't sound like a reliable workaround, but I've had some of these new parts from Richard laying around for 10 years (life happens) and if this one was a mismarked part number, I'm probably just out of luck exchanging it.
Am I missing something?
