Could someone please help me with the bell crank installation on my new Weber carb?

i'm replacing an old, worn out Rochester and bought the adapter kit. My trouble is the adapter kit didn't come with any instructions and I'm struggling to get the bell crank installed. I need a photo of one already installed or an "exploded" isometric, showing the order in which the various pieces go on the butterfly shaft. I think I've tried every possible order and it keeps looking like the shaft isn't long enough to accept the new bell crank, bushings, spring and nut.

Any my help would be great.

Thanks
