Cold weather use!

  If there's a problem with the accelerator pump piston, it will not cause a rich condition, but rather a lean condition on acceleration.

  All the round objects in your latest picture are gaskets made of fiber, copper, or aluminum, except maybe the small, lower left one, which goes between the choke housing and the bowl cover on the 2GC. Again, not in the carburetor, not exposed to fuel, and if broken or gone will only result in a small vacuum leak (causing a slightly lean condition) and cause the choke pull-off not to work properly. It would not affect the choke once the choke begins to warm up. But then, you mentioned the 2G, which doesn't have this at all.  BW

I hate to disagree, but I do. I've overhauled Rochester carburetors until I could do them in my sleep, and don't remember any o-rings on the power piston or power valve, or any diaphragm of any kind anywhere. Nor does the picture you posted a link to show any. If the power piston is stuck in the down position, it would cause a rich condition.
   I will admit that there is one rubber part on the carb (not in it), the idle vent valve, that will have no effect on the carb's operation, in fact it was eliminated on later carbs.     BW

You may be needing to keep the choke closed for a longer time to aid in the warm up, that will cause some fouling of the plugs. There are also a few other things to consider.  1. If you are running a WO, there is no rubber in it. 2. If moisture is condensing in the fuel it could be freezing in the carb passages and/or the Venturi. 3. Make sure your heat riser valve is functioning correctly. 4. If everything is right, then you may just need hotter plugs.

About 7* F earlier today with a windchill in the negative zone.  She isn't a stock much of anything, but it is all Jeep.

No not at all. This is extreme weather for all of us but you guys certainly got it worse than we did.

Different areas have their strengths and weaknesses. For example up until the embarrassing Super Bowl mess TXDOT had only a hand full of snow plows in DFW. They have bought more BUT not nearly enough for us to be able to handle a serous snow storm. I don't think I have ever seen a snow blower except for on TV.   One of our main problems is we rarely get just snow. Usually winter storms are ice first then snow. The last storm we had before Christmas the ice was 3-4"+ thick. They were using road graders with what looked like iron spikes welded on to try and break it up. The sun would start to melt the ice but it stayed below freezing so what we ended up with was a glaze of super slick ice that was hard to even walk on much less drive.

I love the videos of you guys blazing through the snow drifts. That looks like great fun.

I think I would seriously freeze to death in weather like that.   It was 12 here this morning with the wind chill around zero. Saturday it was around 70. This morning was the coldest day in 3-4 years.   I started my F250 about 30 min before taking the kids to school. (I know - very wasteful and not very green friendly!). I was a little nervous that I didn't plug it in last night but it cranked fine. I did notice that it idled higher than normal for the first 45 min of my 1.5 hr commute and you could hear the turbos more.

I do love to snow ski but that is way different than wrenching on the Jeep or driving it without a heater. Do you block the radiator with card board or something to restrict the airflow?   

I just read that many flights at DFW are delayed due to frozen jet fuel. Wow. 112 in the summer is miserable also but we can still function.   12 not so much.
