Mostly of intent -- a choke is taken to be in a low-Q circuit, a coil may or may not be. If it's marketed as a "choke" then you don't want to use it for tuning or impedance matching; if it's marketed as a "coil" then inspect the specifications closely before proceeding.

And if the specification calls it a "choke coil"?

Then its part of the "early choke pull off" that was so popular in cars in the 1970's. Its just a heater for the automatic choke thermostat.
Smartass.
Then they're using like a choke, and they recognize that it's a coil.
I had a car (Mazda) that had an electromagnetic 'brake' to hold the manual choke knob out until the engine reached operating temp. Then, a thermo switch cut power to the coil and a spring pulled the knob back in with a 'pop'.
I wonder if these are called 'choke holds' or if that's just something our local cops use?
