I concede; it may well be K-Jet, and I’ve attempted to amend the subject title accordingly. What threw me was a thermostatically controlled idle air supply - not an electronically modulated shutter as described on a lot of online overviews of K-Jet - and the first result from Googling the part number on the fuel distributor head, ascribed it to KE-Jetronic.

Either way, I’d like to set the butterfly right, reassemble the whole fuelling/intake side and see how it runs with one less vacuum leak. The whole motor was bathed in grease and oil when I started; the SLS pump supply hose and power steering pressure hose had both failed prior and only perfunctory cleaning done in repair. Hoping the cam box is still sealed!

I’ve attached an image that encapsulates the general state I received this car in. How it could happen - I have no idea. Removed, cleaned, straightened, checked, lubricated and re-fitted.
