It appears that there are two types of metering kits. One with the machined slot for the lever to clip over and one just a plain pin. The original carb had the latter, so was assembled correctly.
Some good news!
I just got the engine running. I had it running for some 5 or 10 minutes. It is running poorly and required both needles to be almost closed to run at all. I conclude that the metering lever is now bent far too high. My next step is to adjust it down 1 mm then test. More if found to be necessary.
