GMNZ bulletin 166 july 1975 ( remember NZ allways behind Aussy dates ) shows LH 308 carb with man trans blank off plug on lower rear port where auto trans modulator line would go , Bulletin also lists 1 part number for 308 carb !! Later bulletin 23 sept 1976 lists quadrajets for Holdens , 7029281, 7029282 , 7041281 , 7041282 , 7043283 , 7043284 , 7045281 , ( 68--75 ) 17056280 76 -- . Mark .

Done some more research. At this stage it looks like early HJ auto (pre canister) used the same carb as the late HQ auto ie 7043284. Early HJ parts catalogue confirms this too ie lists the same carbs for late HQ and HJ (presume 7043283/4). Later HJ parts catalogue lists 3 x different styles of carby - early (as per 10/74 catalogue), middle with ADR27 (presume 7045281) and late for ADR27A (same as HX).

The only confusing bit is the middle HJ with canister (and ADR27). The vacuum advance port on the front of the earlier auto carbs (7041282 and 7043284) is connected to full vacuum. However in the 7045281 carb this same port appears to be a ported vacuum port. On the auto 308 it has the canister connected directly to it, and on the manual there is a T-piece for canister and distributor vac advance. On the auto the dizzy vac advance is connected to the port on the rear, manual has this plugged with a bung. What I dont understand is why different carbs are listed for auto and manual in ADR27 HJ when they appear to be the same carb? Maybe there is something else different on the auto carb, as you say Mark like lower rear port for auto trans - however I thought this went onto the Xmas tree at the back of the manifold??

Heres the numbers off my 8-75 Statesman carby which I have no reason to think its not the original one.

7045281
0175

my 9/75 HJ Statesman is still running the original unrestored engine the carb reads 7045281 and 8894 or 3394 hard to read.

That would be correct for a 1975 HJ with a canister. Not correct for a 1974 though.

7029282 ZB (earlier have 29282 ZB as they aren't Rochester build) is the auto HT-HG 308 carby. 350 auto is 7029284 ZD (early is 29284 ZD). I've only ever seen two of these, one early one (probably Carter build) and one later one with the 70.

Can you send me a photo of the numbers?

I'll PM you my email.

It is a strange combination of code and date code to be missing the ZA. There were no 308 manuals at all early in HT (only auto) hence why I believe there are no 29281 carbs, most of these past about 2009 have the 70 on them, but I've not seen a broadcast sheet code missing outside of very early HT.
