Need to buy rebuild kit for my 74 Spitfire Stromberg carb, how do you tell what model it is? The only id numbers I can find are on the air intake flange and they are BT274. Here are a few pics to help determine what I have.

Well I can't I'd it.

It should have a brass tag in it.

It has been apart before. Note the cam out on the top screws. FYI there is a correct tip size for those screws.

That's not what I was wanting to hear...not from a '74 car, it did come with an auto choke as part of the parts???? Brass tags??? people have a hard time leaving those on the carbs!!!!!
Oh and James those rounded holes aren't from me either. Just saying!
I do have another carb from a parts car I bought but they do look a lot alike any id on this one? see pics. This was from a 1300 so James your pics confirm this right?
So if I buy a kit good for multiple Stromberg cd carbs from Auto Rock, would you think I would be successful and getting most of the parts? Anyone ordered from them?
Any pics of the carb that should be on my 1500?

I think your plan will work, if the kit from Rock auto is the same as the one I got from Spitbits. One note, I don't think any of the kits come with the parts needed for the bypass valve. Those have to be ordered separately, don't know if Rock auto carried those.
the bypass valve should be rebuilt on any of these cars to make sure its working properly. If it's not working or cant be adjusted properly, it can cause issues with set-up and running. Some folks have blocked it off, but I think it should be made to work properly.

Also looks like those two carbs are the same functionally. Both have manual choke (a good thing IMO) and the same adjustments on the opposite side of the carb. Hopefully you don't have to use parts from both to make one good one, but it's nice to have the option.

Willy,

That is a Zenith Stromberg 150CDSEVX serial #3612 which is correct for a 1974 Spitfire 1500.

You should contact Joe Curto and buy British SUperior kit # 5365 which will do any 150CD carb. You also
need to buy the kit for the deceleration bypass valve #BP-014 as it only sold separately.

Your other carb is a Zenith Stromberg 150CDSE serial #3336 or #3427 (only difference is the needle) from a 1971-72 Spitfire MkIV 1296cc engine.

Where did you find the serial number to identify it? I have Stromberg on my 1970 and we are having a tough time identifying it as well.

Steve,

Years of experience building ZS carbs. Up to the early 70's the number is stamped on the body, usually the intake mount. After that they went to the brass tag that breaks off or gets lost. Here
you'll notice a small cast aluminum lever under the linkage. There are 2 ZS150CDSE types with that switch. If steel, it's fixed, non-adjustable and would be a ZS150CDSEV. The aluminum one is adjustable and is a ZS150CDSEVX. ZS150CDSEVX are 1974. ZS150CDSEV are 1973.

1970 Spitfire Mk III have a unique linkage that uses the ball and socket rod. The serial number will be stamped on the intake mount or side body somewhere. It should be #3277.

Just for reference I had put together a list of ZS Carbs, Vehicle and Original Metering Needles.

Thank you as well to both Daves!

So it's looks like I have the 150CDSV which if I read correctly has a needle that is no longer available. I have been thinking about rebuilding this carb, but based on needle availability think I should just hold off?

Steve,

B5AY is Victoria British part #3-630.

If you order stuff from Joe Curto I'd venture a guess he has it on the shelf. Just give him your carb #.
