K1 bodies different, (not sure in what way),
K2 to K7 listed as exact same part number with Robinsons Foundry as are all the ancillary components.
copied this from another thread

I think the difference is in the fuel rail but I'm sure all models are interchangeable. What do you mean by "drive has gone"?

Maybe @mitch  means the Secondary throttle valve actuator (STVA).

Fairly sure they're the same other than the the fuel rail being made of steel on the early ones and aluminium on the later ones, or vice versa

There is no choke. If you mean the second butterflies those are the secondaries that limit airflow at lower revs to speed up the gas speed & make it run smoother.

Choke, secondaries, same thing really.

What you'll find if the secondaries don't move is a magnet has dislodged in the STVA. Easy fix but you need to separate the throttle bodies.
