[Healeys] Starting a BJ8

I recently discovered that pulling the choke know out then rotating it
slightly holds it in place.

Good info.  I'll add one more thing: On my BJ8, at least, the choke knob has
to be held forcefully full out; if the return springs are working at all the
knob will slide in a little when you release it.  This could possibly make
the difference between a start or not.

I think it's a feature of those 2" carbs.

The air speed across the jet is quite low at cranking speed, much lower than
with HD6's as the 8's have 30% larger choke area for the same volume of air
being pulled by the induction.  As a result there is a need to get the jets
pulled as low as possible to get fuel into the throats.

The starter fluid trick seems to confirm that.
