And Elvis was sitting next to ln1gaw in the spaceship, which I thought
was kinda weird, but then they turned to me and said:

There are no static timing figures stated for late-model Minis, you are
supposed to always adjust the timing dynamically with a strobe light.

A rough static setting of around 5? BTDC is usually good enough to get
the engine to start so you can use the timing light.

Points gap:  0.35 to 0.40 mm

Ignition timing (vacuum advance disconnected)

Low compression engine:   8? + 0? -2? BTDC at 1500 rpm
High compression engine: 10? + 0? -2? BTDC at 1500 rpm

If the motor is in perfect condition and your fuel is identical to what
was sold in the mid 1980s when they decided what spec to set, then the
original factory setting would be a reliable guide.

In practice, it's really only a starting point; start at about 5deg,
advance it a little at a time until the motor pings a little, then
retard the ignition a bit until it stops. Make a note of where it is for
next time.

The points gap I don't remember (it's been years since I touched
points!), but if you have a dwell metre, the dwell angle should be about
60 deg.
