Exactly what it says. Most cars do not have a choke, only older carborated ones.

Manual choke has a cable that runs into the cabin. When starting with a cold engine, you manually engage the choke by pulling on it - and manually shut the choke off again once the engine was warmed up.
Automatic choke is basically the same, except that the cable is connected to a metal coil located usually on the manifold. The coil tightens up when it is cold, automatically pulling on the choke cable. As the engine (and that coil) warm up, the expanding metal coil pushes the cable back again.

A manual choke had a cable going to the dashboard. The knob was pulled when the car started, then pushed in when it warmed up a bit.
The automatic choke has a spring or other device that opens the choke plate when the engine starts warming.
My dad told me there was a big problem with manual chokes, as women would pull the knob and hang their purses on them.

auto engines work differently at cold starts than when warmed up. so to crank the vehicle on a manual choke car you must first pull out the choke lever and attempt to crank the vehicle when it hits you then push in the choke half way and let er warm up and then when shes running smooth you push in the choke all the way. sorta like starting a weed eater, with a auto choke the car when cold has the carb flap shut with a spring mec that looks like a clock winding. or a wall thermostat cheap one anyway when the heat starts to come into the manifold on the motor the spring expands and opens the flap on the carb to let her idle smoother. no need to mess with the carb. get it?

You know how a choke richens the mixture for cold starting? With a manual one, you pull a knob and have to judge just how far, according to the temperature. You also have to ease it back in as the engine warms.
The auto choke does all this for you, by sensing the water temperature in the engine & adjusting the choke accordingly. You don't have to touch anytthing.
Hope that helps.
