    Default the unofficial CFI choke thread

    The CFI choke works simmilar to that of a carb.

    When its cold, you press the gas to the floor before starting the car. This opens the throttle up, allowing a mechanism to catch, setting the choke.

    For CFI, the end of the throttle shaft sticking out has a lever on it that simply catches on another lever thats connected to the choke thermostat.
    The choke thermostat is the black round gizmo that sets its lever to a more extreme angle the colder it is (or is supposed to, at least).

    Once the car has warmed up and the computer sees fit, it fires the TKICK vacuum solenoid, which simultaneously activates both the VOTM (throttle control) and choke pulloff.

    Observe the following pics and video... if your choke mechanism doesnt look/function like these examples, it prolly dont work

    Choke idle level most likely can be adjusted with the screw visable in the pics, but dont take my word for it.
    I heard somewhere you can also loosen the choke thermostat and "dial" it one way or another.

    The video:

    you can see as I open the throttle, it catches on the thermo-coil lever.
    My finger does the job of the choke pulloff, releasing the choke.
    Lighty taping the gas after the car has warmed up should also release the choke, unless the thermo coil system is malfunctioning and has not warmed up allowing its lever to drop.

    Nice work

    The screw adjusts how fast the idle is.

    If you loosen and adjust the choke thermostat, the black round gizmo, that adjust what temperature everything happens. Turn one way and choke closes sooner, other way and it opens sooner.

    So if you have cold start problems, see if choke is closed after opening the throttle completely, if not, adjust the thermostat so it is. If it is closed, but idles too slow, adjust the screw.
