TOY: Idle/choke Question

[FC3S88RX7@xxxxxxx]

Ok gang, Now that the truck is finally road worthy, and the winter is over 
[figures...], i have one small question.  The truck is an 87 22R 4x4. Upon 
startup-after 2 strokes of the gas pedal in cold weather-the idle will 
sometimes shoot to 3400RPM, but usually right around 1900.  The odd part is 
that the choke climbs the longer it runs[usually to 2200-2300], and you have 
to keep tapping the gas [total of 3 or 4 times] before it settles down to 
950-1000RPM.  You can tap the gas once, and it will come down, but it 
continues to climb until its warm.

This seems simple, im just not Carb-friendly ;-)

Thanks, all info appreciated.
