TQ Identification

[brasil]

.. Hello guys..

I ve bought a TQ Carb for my 66 Coronet.... the car looks good, but I can´t Identify the carb... there is a
Metall Tag mounted on the rear right corner...that says C 6046 on the base there is a number STAMPED
9097 9 and below that number there is a 82 6

On the top cover there is also a casted number 6-2141

I search here in the forum..and also in the internet...but I can´t find the C 6046 Carb.... or am I on the wrong track... with this number... ?

Perhaps someone here can help ...?

Thank you for reading my post

Perhaps this guide will help. The 9097 seems to indicate that it came from a 1976 400 engine.

A search for "6-2141" shows several on eBay, also for 1976 engines.

... thank you Photon440
Sounds interesting...because I bought the carb at rockauto... according to their catalog the carb should match for a 73 Coronet with 440 cui engine.... hmmm.... tomorrow I will install the carb on my 440 cui engine...and I hope the carb will work... with the set up it has currently...

The C6046 is the Autoline rebuild carb part number and the 9097 is the carter OE part number

...@bm02tj... thank you for your Tip. Now I know, why the carb runs a little lean ( AFR 16.5 ) while cruising... the carbs belongs to a 400 cui engine... WOT is o.k 11.8 -12 .0 AFR... Idle is also good.. but I think I have to change the primary jets... right now I have
the 0.098 jets ( 4098 ) and the 2086 Needles.. sadly the needles or no longer for sale...so I think if I go up to jets with 0.100 inches or 0.101 inches the carb will run a little richer....

Does someone here perhaps has another advise for me ?

Thnak you Juergen

The 6-2141 number is the air horn (this is the top assembly) part casting number only, thermoquads have the part number stamped on the left rear or the throttle base plus the date code. Also, older air horn assemblies are 6-2124. also you may see a large number 3 or 4 stamped on the air horn, I believe this may be a revision number. The date code you found 82 6 I believe means it was made on the 86th day of 1976. You can read more on the thermquad sticky, http://www.forbbodiesonly.com/moparforum/showthread.php?38460-Thermoquad-Guide& it shows as 76 400.

FYI, you can use later or older model carbs on many different engines, however, there are some differences, carbs with out bowl vent or bowl vent valve are later models and typically California emission carbs and use internal venting for the bowls. also some have altitude compensators, solenoid activated bowl vent valves, and when you get into the 80s versions, you start seeing the computer control options added.

Quadrajetparts.com sells jets and they also have two sizes of the metering rods available.

My carb has no california emission stuff.... but as I wrote he runs a little lean...

...I orderd some jets yesterday..after doing some mathematics.... my currend primary jet is a 0.098 so the total area is 0,007543 square inches... the needle is 0,069 ( econ tip ) that brings me to a 0,003739 square inch area...
The 0,007543 minus the 0,003739 equals 0,003804 ( that is my current net area of my primary system )
I need to go 10 % richer with my AFR..so the Target should be @ 0,004185 ....

using a 0.100 jet brings me to 0,004115 square inches

using a 0,101 jet brings me to 0,004222 square inches.. ( that´s a little more than 10 % )

So I will use the 0,100 jet first...and see how it works.... if the carb is still runing to lean I will go with the 0,101 jets...
