Hi Alan,
I have one of the few Healeys (one of only 1500) to have the thermo choke.
The previous owner fitted a switch to the dash and just left the thermo
switch in for appearance and to blank the hole. I find it useful to be in
control of the mixture and left it that way. Although a manual choke would
be better in that you can contol the range of mixtures as the motor warms
up, I love the novelty of the device and the fact that it represents one
attempt of the factory to move forward with their design, albeit a mistake.
I would leave the device in and if you are finding it frustrating, instal a
switch in a subtle location rather than replace the thermo switch.
cheers,
Mirek
