Hi Gary

 

Mine car is a 10/72 Adelaide. All three brass tags are 2393 over 3547. I have no reason to suspect that they are not original to the car.

Hi John, no mate his is the Adelaide car, he looked for you at the Canberra torana show. Said he didn't see you or pop's though. My memory isn't that good anymore John, i can remember doing it, but i couldn't remember if it was a Brisbane car sorry mate. That time has gone so fast, Gary.

Hi Gary

To answer your question correctly we need to determine which batch of carbies you have on your 9/72 Adelaide built LJ XU-1.......

Frashes car has the 3rd batch of carbies used in 1972, these have the brass tag 2216. The 4th and 5th batch of carbies used in 1972 have the letters " TC " stamped into the face. The 4th batch of carbies " TC " were generally used on some 8/72 & 9/72 Adelaide built LJ XU-1,s and have the brass tag 2293, while the 5th and final batch of carbies for 1972 have the brass tag 2393 and are generally found on 11/72 LJ XU-1,s and some very early 2/73 LJ XU-1,s.

In 1972 & 1973 there were a total of 8 batches of 175 CD Strombergs used on the LJ XU-1,s. They are in order from January 1972 through to September 1973.

Baz, Can you break the code ? ? ?

Hi

 

A number of years ago II bought some carby parts from Gower & Lee in the UK (the worldwide distributor for these carbys and parts), I asked them about the numbers on the tags - their response was " The part numbers on the brass tag relate to the build specification of the carburettor".

 

I understand from this, that the numbers are only for identification purposes.

so does that mean that whilst they are practically the same carburetor body there is a small variance to the internal parts  and hence they needed to give a new tag to the build of the carburetor which left there manufacturing facility.

 

I assume that there MAY BE A  manufacturing change ( which i am not aware of in the style of the body ) 

 

as this was a controlled operation it sort of makes sense that the tags defines the internal parts, needles jets etc 

 

Ps i don't own a xu and have not looked in depth at the tags on the xu1 but could the above make sense as too why there is changes ?

There are two code numbers on the tags. The top number is the assembly date code. The bottom number is the model application code.

[grumpy xu1]

I think you might not be on the mark Dave, as mine are by memory 2216 front 2217 middle & 2216 back & the Adelaide xu1 in the question has different number in the middle with the 2 end tags the same as well, more like a linkage set up to me as the middle pull rod is different, Gary.

Hi Gary, no problem mate.

I always thought the upper number on those tags was the assembly date, happy to be corrected.

 

Basically the only difference in a set of carbs is the front carby has the brass vac advance port tube fitting and the other two have a brass hex head plug screwed into the port.

 

Cheers

Dave.

+ the pull rods with the top adjustment point mate ! Gary.

[grumpy xu1]

Hi Dave, that's what makes sense to me mate, I have seen a few sets that way. I would assume that the 3547 ect was the jetting ect, Gary.

I think you will find the two adjustable and one fixed length throttle pull rods are part of the throttle linkage assy not part of the carburetor assy as it came from Zenith.

 

[FLY_AGAIN_XU-1]

there is no tags, but on the face of all three  they are 226t

 

thats not on the above list ?

 

Grantly, the above list is a list of brass tag numbers, they are actually a date, yours has no brass tags. HOWEVER it sounds to me like you have a matching set of genuine 8/72 or 9/72 Bathurst carbies. The brass tags on them if they had brass tags should be 2216-3547, the 3rd batch of carbies used from August 1972. Now all that is left to do is verify the cast dates under the fuel bowl. Should be either 4/72 or 5/72.         GOLD

4/72 A 110 on my 9/72 brisbane built xu1 carbies inside the fuel bowl, Gary.
