This was a very real emergency and a fantastic opportunity for me to review my own level of training. I made many mistakes but we landed safely with no injuries or damage to the plane, and that is ultimately the objective in any emergency.
Aviate, Navigate and Communicate (ANC).
I welcome any feedback!

The problem turned out to be that the main jet in the left carburettor was blocked, which is why I lost cylinders 2 & 4.
