I know it's a long shot, but before I put in another order to the US for Dell parts does anyone have laying around a CB Performance Dellorto linkage.
If you don't know what I mean it's the double threaded shaft with a swivel linkage at each end. I busted one trying to undo an end. It had been previously done up too tight to compensate for a stuck butterfly on the other carb.
Here's a photo
