Yes, I will go that route, thanks

It's a 1930 Buick model 40, assembled by Holden, sorry for the time delay when answering

I need either a replacement distributor or new bushes as my unit has excessive movement on the central shaft. Can anyone can help?

Thank-you Jon. I will do as say and if I've still got my mind set of replacing the carburettor, I'll try the Carter. many thanks Steve

Thank-you for your reply, I have checked the net using images and have found the carb on engines that looks identical on a 6 cylinder grey engine, amongst others. I'm just wondering whether the stamp on the carb saying aviation corp might indicate that this carb was made during war II when they made these carbs for aeroplanes and boats, possibly. The red engine carbs although similar look a bit different though it could as you say be other problems such as fuel pressure, but I am keen to try another suitable carb If I knew the best option, that red engine one looks promising. The car is Christchurch UK not New Zealand unfortunately Any advise you or others give is very helpful, I have never used a forum before but I have learnt a great deal from these posts Steve

The idea that the carb was made for another Holden car sounds right to me, I am hoping that Jon will be able with the sparse info I've been able to give, to shed some light on the carburettors suitability. The car has never run with much acceleration or pull since a brought it, but in fairness it did not die on me until when visiting our local garage a mechanic decided he could make it run better by adjusting the carb---it has never run the same again, but know he meant well. Thanks for your reply Steve

Thanks for your reply Jon, the flipped manifold certainly explains it, we thought perhaps it came with this carburettor for a moment! I've done some digging around my paperwork that came with the car, The engine no. is 226568 but as yet I cannot find any record for 1930 series 40 engine numbers on the net. But I do have letter from the last owner in (3 in total) explaining that they replaced the marvel with a down draft carburettor and basically the old parts were under the seat. I personally believe the engine to be the original as it was partially restored over here by the previous, now deceased owner, and I know he didn't change it, but of course that still leaves 70 years unaccounted for. If that is correct the cu in is 257.5, I understand this to be 4219 litres, wow. The stamping on the bowl it is problem, please see pics, I have looked all over bowl without finding the circle stamp. It has an adjustable main jet on the front I Much appreciate your effort Jon Steve

Thank -you for your replies, I can get the pressure tested, and I too suspect a sticky valve as the manual suggest this as one of the principal causes of uneven running. The distributor is quite firm and runs freely on its advance and retard mechanism. The car at the moment starts on the choke and accelerates to high revs, but with the choke -in when hot, the car runs very erratically, basically when you take your foot off the gas it will as like dieh After a period of backfiring out the exhaust. The exhaust is quite clear with no smoke visible. If you pull out the choke when running hot the engine will also die. I'm sure this is normal We have cleaned and blown through carb, and also purchased an enlarge main jet, checked the spark, rotor etc The electric su pump used to run through and mechanical pump but I've rerouted it straight to the carb as I suspect some debris from its old diaphragm was working its way into the carb. Jon thank you for the link it is indeed a treasure trove of info. I've upload a pic of the original replacement carburettor, and studied it, it is a Stromberg Holden. I frankly do not know what difference this makes only that Holden manufactured the bodies on the Australian assembled cars. Any more help greatly appreciated. (I will upload a pic of the car)

Many thanks for your response, it has an electric 6v su fuel pump, with original an distributor I do not know the pressure being delivered, other than it shoots out, so that is a path to investigate. Although the valve clearances are ok, it might well benefit from an inspection of the valves. If you can bear with me I will upload a pic of the carb tomorrow which has very little to identify it, there is quite a time difference as I am in the UK Steve

The car is a 1930 series 40 with a straight six cylinder engine, 257.5 cu inch At present the carb I have on it is a single barrel Stromberg Thanks for responding

i have a 6 cylinder Buick model 40 which was assembled in Australia. the car should have a marvel carb but this has been replaced in the distant past with a Stromberg I've owned the car for five years but it has never run well, it often backfires and achieving a smooth tickover was not possible. I assumed that another identical carb might do the job but this has made matters worse. I believe as everything else I can think of has been done that it is fuel starvation. Could anyone suggest an alternative carb I might fit?

Many thanks for your reply, but looks like I've fixed the problem with a local engineering business who assure me they can duplicate corroded rail and 'cut and shut it', well this will be a great result, but I am most grateful for your reply.

Please, if anyone has a spare windscreen surround please say, mine just cannot be welded and looks like quite a task to make to new one.

Hi, Have you got the windscreen surround, as mine is rotten and beyond repair? many thanks, and sorry to trouble you if you have already everything.
