Resonantly purchased some 73 xu1 carbies,the numbers on the face of the body where the air filter backing plate go's are no1 T226A,no2 T226A and no3 T226B.They also have TCX on them aswell but whats the A and B stand for?Been talking with a forum member and has seen over the years that a every matching set has T226A,T226B and T226A.
Holden must of put the T226B carby on there for a reason.Would be very interested in hearing from any fourm members that have the 73 xu1 to see if they have the same.

A = adelaide ?????
B = brisbane ?????
thats just my opinion dane...
probably wrong but the 150s are
also stamped 128 A and 128 B and i sort of
guessed it meant that the 128as were
found on early LC xu-1s and the 128b were found
on the CK block cars....maybe should get in touch with bruce...

Yeah have been talking to Bruce.
Maybe right Johnno but wouldn't you think if the A=Adelaide and B=Brisbane then a Brisbane built car would have all Bs and an Adelaide would have all As???
Hey Gong did you mean that your 73 set are the same as what I quoted?

Mine are #1- T226B #2- T226B & #3- T226A as they came off.
I'd hope they are original, havnt checked the dates on them
yet but BM & Bruce confirmed the number on the tag was right
for the build date on my Torrie.

i,ve heard that it is quiet common that brisbane cars had 2B,s and 1 A carbys don,t know why.
also is there a differance in the bathurst 73 carbys compaired to other lj xu1,s other than the numbers?

original carbs.

Craig I think all 73s had the t226s on them, and there are no differents to early to late,but I'm only a trainee on this so I could be wrong.i,ve heard that it is quiet common that brisbane cars had 2B,s and 1 A carbys don,t know why.

there where 2 batches of the 1973 carbys the a batch and then the b batch, it is like everything with holden what thay grabed from the shelf is what you where given,,,
dane my first carby was t2268 then the other 2 where t226a, thay cast all 73 carbys in janury and thay had alot of cars to supply for,, i am not sure about the fact that brizzy cars had 2 bs and adlaide had 2 as,,, i would think it is another thing we need to sort.
cheers gong

Here is an idea, only one carby has a brass hose connector for the vacuum advance hose, where the other two carbies have a brass plug.
It looks like the A if for the vacuum hose port and B is for a blocked vacuum port and were each complete when taken off the shelf for assembly.

Every chance you've nailed it I reckon 
if you have?
There would have to be a small difference.
I was thinking linkages.

The initial 500 2/73, 3/73, 4/73 % 5/73 XU-1,s ran the 226 TCX carbies
While the 288 6/73, 7/73, 8/73 & 9/73 Bathurst Homologation Specials ran the T226 TCX carbies
Note the differences in the housings....................

2 = 1972
38 = Week 38
3 = Day
3547 = Metal Fuel Lines
3521 = Rubber Fuel Lines (Early 1972) 949,s
The carbies used on the 500 2/73, 3/73, 4/73 & 5/73 XU-1,s were basically identical to those used on the 1972 cars though the TCX depicts them as 1973 carbies. TCX = 1973.
3 = 1973
13 = Week 13
3 = Day
3547 = Metal Fuel Lines
3521 = Rubber Fuel Lines (Early 1972) 949,s
2 easy Gong...................

Just checked my dates & numbers on mine
Date is same as pictured
T226B/A & TCX on the face
3133 & 3547 on the tag
But I notice that my vacuum hose fitting is a little different
& what dhufish said about B being blocked, well the fitting is
on 1 of my B carbs.
They've been rebuilt & they were marked well so just hope the
carby bloke reassembled them back how they were.
cheers Jono

Here's a reply from my mate in the uk
Hi Kev,
I know that on old Solex carburettors from the 50's & 60's the numbers & letters relate to the production year and month but on the Stromberg's I haven't a clue. I've just asked a colleague of mine who worked at the old Zenith/Stromberg factory in the 1970's and he thinks it's to do with batch numbers but doesn't remember if this relates to a date. I've also asked BFS who took over Zenith production in the 1980's and they also don't know.
Looks like it up to us to decifer what we have here
