[Healeys] Healeys Digest, Vol 11, Issue 93

[Mirek Sharp]

As Gary said that is the sending unit for the enrichment device -
technically it is not a choke as it injects fuel directly in to the intake
manifold to richen the mixture, as opposed to choking the air intake on the
carbs (or lowering the jets, which really isn't a choke either).  I think it
was closer to 1500 units  that had that thermo-electomagnetic wizardry, my
'59 3000 being one of them.  It was also fitted to Jaguar saloons of the
same vintage.  They work well excepting that once set up they only provide
one mixture - they are either on or off, rather than being able to adjust
the choke as the car warms up.  The sender unit is prone to failure but
Burlen offer a replacement.  However I think most cars with this device
simply disconnected the sender unit and installed an extra switch on the
dash to control it.  This had been done on mine and it is more practical.

That s the sending unit for the thermostat operated choke. They quit that
after the first 500 units, Gary
