Carburetor Technical Information Thermoquad Background The Carter Thermoquad (TQ) is a large four barrel carburetor with small primaries and large secondary bores, referred to as a 'spreadbore' design. Thermoquads share the same flange as Rochester Quadrajets and Holley spreadbore carbs but use different flange gaskets. The main body or float bowl of the TQ is made of black phenolic plastic which is meant to keep the gasoline cooler than a conventional metal float bowl. Carter Thermoquad 9046S - uses kit, floats and choke pull off Thermoquad Applications Thermoquads were used as original equipment on mostly Chyrsler products from 1971 to 1985. A few Lincoln 460 CID engines in 1974 used an electric choke version of the TQ. IHC used TQ's from 1974-1980.
Australian Fords also used these carbs in the late 70's and early 80's. The carb was also produced in aftermarket versions up to 1000 cfm. A handy way of distinguishing large TQ carbs used on 440 CID engines from those on small block Dodges is to look at the primary throttle plates. Small carbs use aluminum primary throttle plates, whereas the larger CFM carbs have steel primary throttle plates. Service Information The TQ is a sophisticated carburetor that uses some of the same design concepts as the Rochester Quadrajet, including a secondary air valve/variable area secondary venturi that allows the same basic carb size to be used on a range of engine sizes. Spec sheets for 1970's Chrysler carbs are.
The Carter Thermo-quad has gained a rather unpleasant reputation for being. ON MANUAL TRANSMISSION CARS ONLY: Continue past the basic pump. See the Service Parts Information section for details on parts and part numbers. Specifically the Carter Thermo-Quad service manual.A Carter Thermo-Quad Guide Page 4 of 31 The fuel inlet on the CS and the 78-84 OEM units was located in the rear center and the 71-77 OEM and 9000 series have the fuel inlet on the right rear side.

I have and it's ugly and finiky to deal with. I even did a set up with an electric choke useing the stuff off of an AFB mounted to a pair of 'L' brackets on a plate under the carb. For a manual choke, it is easier to go to the other side (Drivers) and use a 'L' bracket and the big hole to mount it. Now use a screw down holder, like a manual choke cable holder for /from a Holley or Carter and drill a mounting point down low on the bracket angled upwards to the top of the carb. Disconnect the linkage and use the existing hole to operate. I think I may have a picture around.
If not, Later after a vote, I'll go back into the garage and recreate it. It was easy enuff.

It was easy enuff. You have to forgive me, vaction came and dominated my mind set. In order,; The first picture shows a simple metal bracket I had layin around. I bent it at a 90. angle, drilled a small hole at the bottom to attach a stock cable holding bracket part from A Holley or Edelbrock, I'm not sure, there all the same really. I'm holding the scew driver to position the cable clamp bracket at the approx angle it will need to be so the cable is angled to move the linkage smoothly without binding. DO NOTICE that the carb is missing a linkage part.
This is where the cable will attach. Picture 1 & 2. Notice that I used a simple nut and bolt with washers to attach the 90. bracket to the hole at the rear drivers corner of the carb. This hole is found on all T-Q's, or that I have come across.
The pictured screw driver in pic. #2 doesn't show so well that the hole below it is not exactly in line with the one above. Just a nut and bolt with washers/lock washers will do just fine. Picture #3 shows a LD-340, non -Chrysler/Direct Connection model with a flat spot on the passenger side. IF you have this, it may be possible to purchase the pictured Edelbrock divorced choke and use a coat hanger for a rod to attach to the correct side of the T-Q in the correct OE spot. A small nice can be cut into the coat hanger to use the OE clips to retain the coat hanger.
