Let me preface this thread on the fact that I am a Carb-retard.
The problem I am having is cold weather starts. The jeep just will not start when cold. The jeep is a third vehicle and only gets driven once a week this time of year and only drives to the dump and back (4 miles round trip). I have noticed that the choke plates on the carb are open when I go to start the jeep and if I remove the air cleaner and physically close the choke plates the jeep starts right up first try. Pumping the gas pedal does not close the choke plates.
Is this just a linkage adjustment problem as the pumping of the gas pedal should close the plates or something else.
The jeep is a 89 YJ 6 cylinder with 89k miles on it. The carb was installed over the summer and has not been running right since. Even during the summer the jeep took a couple of cranks to start. Once warmed up the jeep will always start first turn of the key.
Any thoughts would be appreciated

It is hard to diagnose problems like that over the computer, but...
Are you sure the choke linkage is connected properly?
One pump of the gas pedal should set the choke.
Do you have the electric choke, or is it supposed to be a manual cable choke? If it is manual, you would have a cable with a knob inside the cab of the Jeep.
When you take the air cleaner off, push on the throttle cable (at the motor side) to Full Throttle. Watch for any levers/mechanisms that should move around to set the choke plates. Like Bob said, the thing is probably all gummed up from sitting.
I never had any issues with the choke on my Weber, straight out of the box.

It is an electric choke. The problem is when you press the gas pedal it does not set the choke. I am leaning towards a linkage issue because the more I look at it I realize that when the gas pedal is floored the throttle does not open up any where near as much as it appears it should. I know it is a difficult thing to diagnose over a computer but I am getting annoyed with it.

I'd check it out but the cape is a long ride. Maybe someone closer could look at it? Sorry. Bob

hmm my uncles jeep has a weber and i noticed you have to pump the hell out of it to get it to start. I bet the choke doesn't work.
My choke on my jeep is wired open...starts anyday.
You say the butterflys don't open all the way? hmm even when you do it by hand? The butterflys are directly connected to the linkage unless something pysically stops the linkage or butterflies. They should open totally vertical.
