Okay here goes, I just purchased two 4973 1971 Thermoquads which were advertised as parts carburetors. One is complete, one is mostly complete. The air/fuel mixture needles are broken in both base plates. I am thinking am easy out to remove the broken off needles. or drilling and re-tapping? Either way I need to purchase new air/fuel mixture needles. Does anyone know the part# or size of them? I see many years for them but not 1971 which I know if a one year only animal. Thank you !

If the link does not work it is titled:

Carter Thermoquad Club/MANLEY Thermoquads

Can't help you with part numbers, but take a look at the attached section of the Carter TQ Service Manual. If you want the full PDF you can grab it HERE.

In fact, I've got a couple more things sitting on my Web server, so check these out:

1) 1972 TQ Mopar Reference Booklet

2) 1982 TQ Mopar Reference Booklet

There were two types of idle mix screws used, and while it does NOT spell out the details and/or differences for the '71-only air circuit, one could expect this to be a reasonable assumption. Further on, when you successfuly extract what's stuck in there right now you'll be able to measure this.

You mess up buying them pieces of crap
There were many resaons Carter made those carbs for one year only
I hope you do well with them, no matter your intentions are on, with, them

Years ago I was told by a very knowledgeable individual that the 71 TQ's were based off the carter competition series thermoquad's. I have also read the same in several articles. Might be of some help

Maybe he needs one for a correct 340 application. 1971 Thermoquads are a one year only application, guys are always looking for them.

That carb turned strong 340 Stockers into record-holders - like the car in my sig pic.
Many a '70 got '71 trim to take that advantage.
Had one on a 408" SB street Duster that was done by Demonsizzler, and it was utterly perfect.
And yeah, good ones are $$$ to the right guys.

Found these on the bay LINKY part # is per the listing is 30A 207

Thank you !

CAB you know better than that. 71 is the best factory carb ever.

From the stock guys, 71 carb is faster than later carbs. 71 is a total different animal. I one good one from 2 cores to use if I run 71 TQ or 70 AVS.

you're welcome
I do have a old carter book from the 70's and a bunch of carb parts but they are not organized Seriously doubt I would have the mixture screws. Metering rods, jets, a few AVS cores (bare) If you get in a pinch PM me with your needs and give me few days to dig through what's there.
My intent at some point is to try and sell all as a lot

Thank you again TJP!

I liked racing the Max Wedges, street hemis and six pack cars: up:
