Yes. I've suggested it many times, but apparently the use of the Ignore function as well as not reading threads people don't like are too difficult.

Everyone, rather than type up a bunch of Warnings for namecalling, hostile posts and other conflict, I just deleted them all.
Each incident of it from this post on will be met with a vacation without Warning.
I won't repeat my daily speech about not posting in threads that you don't find valuable.

Carburetor Icing Causing The Problem? Maybe.
Now I'm wondering if I could be experiencing carburetor icing while I'm driving it. All I know is when I pulled up to a stop sign or red light it was fast idling at about 1100 rpm. I could kick it down but after just a block or two it was fast idling again (ice holding it open?).
After I applied the A/C putty to my choke housing it appeared to have solved the problem but I haven't taken it for a longer drive yet because my bad fuel pump safety switch may leave me stranded. I'll know more after I get that switch changed.

I KNOW this may seem ridiculous to your TBTR...But why not remove your fan all together if you are driving it when it is that cold....or seriously block off the face of the radiator like truckers do during the winter
The reason is ..I have a customer whose Corvette needs to have half of the radiator blocked off here in the Carolina's and he has electric fans...and one of the two electric fans is disconnected. AND you driving the car when it is 17 degree Fahrenheit...I seriously doubt you would ever overheat if you are driving it...because as you know like MANY of us...when driving it at above inner city speeds...the air is coming through the radiator very well all by itself and not needing the fan to pull it through.
And not knowing if you know it or not but the 1984-1996 Corvette cooling fans do not come on until the coolant temp reaches approximately 226-228 degrees Fahrenheit. SO many times during the winter...I have seen the fan not ever be able to come on.

How old is the choke element? Bimetallic elements do degrade with age such that they produce less travel. That could make it more sensitive to temperature extremes. Is the gasket under the cap in good condition? Have you measured the voltage at the element to be sure there's not a voltage drop in the wiring somewhere?
I have to admit, I'm not a fan of electric chokes. It's a very crude way to do this job. Nearly every car I've had with one needed frequent attention, especially when the seasons changed.

I realize coming up with Rube Goldberg methods of fixing things can be entertaining but have you measured the resistance of the heating element in the choke coil? About 10 ohms is for a new unit, and a used one can go as high as 20, over 25 you need a new one. In addition if the coil is good adjusting the setting for cold weather would eliminate the need for any other fix.

Ram Air Causing It?
I just got my new Carter fuel pump pressure switch installed so I'll take it for a 25 mile drive early tomorrow morning and see how it does. I'm pretty sure its being caused by the ram air after finding my carburetor was ice cold after a 60 mile drive a few days ago
And of course I'll be driving on my 24/20 psi under inflated tires to put a heavy load on my engine.

That's me (no smokes tho'). Works in Indiana winters on a Qjet with most of the choke tower off and a radius to make a perfect circle over where the choke housing intrudes the primary bores.
I think TBTR needs a new fan clutch. Damn thing shouldn't be engaged if it's that cold out !

Trying to HELP you out on the SUBJECT MATTER of THIS thread. I do not need to deal with your comments dealing with something else....that WE all know how you feel...and personally I do not care what you do with ALL of the information previously given....when I am trying to help you....UNLESS you do not want help. I guess you have to get the 'last word' in...as previously mentioned.
WELL...moving to Florida...you should not have to worry about icing of the carb now.
And I guess NOT trying to see how it does with the fan removed is OUT of the question. I guess you might think that I am full of it...but seriously...the 1984-1996 Corvettes with electric cooling fans ...when being driver...never get hot enough for the fan to come on in the winter. If you engine is set-up correctly...you should not have a problem.
