[Healeys] automatic choke

[Alan Seigrist]

All -

Actually, the otter switch has a technical connection with Westlake head in
the Healey.

Ok, you know the bit in the head where the water temperature sender goes
into the engine?  On most 3000s the temperature sender is difficult to get
to because there's this square hunk of water gallery located directly above
the temp sender. That's because this bit of water gallery was designed to
take the Lucas otter switch for the AED.  Prior to this "developmental
improvement", the Westlake head didn't have this water pocket above the
temperature sender, and the sender is MUCH easier to access as a result.
 That means BN6s and some early 3000s had Westlake heads without the water
gallery pocket for the otter switch.

So, next time you are boogering up the temp sender bolt head, you can blame
Lucas and their otter switch (which was famous for its cutting-edge
intermittent-function technology).

Best,

Alan
