So you haven't been using your engine at wide open throttle then ;). Had an issue like this on someone's car. 1/3 throttle at nest. They thought that was just how little power it made; fixing the cable changed their opinion of the car's performance.

Back in the dim dark past I had vehicles with SU carbies. I seem to remember that if the needles aren't centred in the jets they will stick & not drop properly. Worth checking the needle mounting points, which IIRC are spring loaded, (or was that Stromberg CD's :(), to make sure that they are free moving. Can't remember whether there was an adjustment for the jet bases to allow centering. Too long ago!
As previously mentioned, a good clean out of each carby, & careful re-assembly should do the trick.

When I came back to the carby today it was resting against the stops. We can consider this case closed (though when I went to test drive it, she started on 6 cylinders, but I have obviously bumped leads while working on the carby). At least the engine dropped back to idle with the choke off.
Thanks again for contributions.
I will sort the missing cylinders in the next few days.
