One already exists for the 'A' series, use that made for the 998cc MINI,
been in production since 1990. Its a single point ROVER designed system,
should fit a Midget.

Modern EFI systems are not timed anymore, they 'pulse' their injections
towards the valves, to suit the intake requirements. This makes them a
lot cheaper to produce.The ejectors are simply solenoids that the EMS
tells to when to open, and for how long, in mili-seconds.

A lucas effort using WW2 fighter plane technology, similar to that
fitted to the Sptifire Merlin engine, and after to the Shackleton
Griffon engine, ( and many more.) It was a brave effort, but MECHANICAL,
and doomed.
