Hey ,on the Stromberg 97 you can tap and pull them out,what about the 38 cadillic carb?
Thanks
I guess you're talking about the 'Main discharge nozzles'? They will come out, but it usually destroys the seals which are lead, and I have never seen them available.
Thanks Steve,yes the ones behind jets.do you know anyother tips I should be aware of? it's apart and ready to soak in carb cleaner.
Giff,
If you are talking about the tubes that go behind the jets into the venturi ( the brass ends stick out) they come out
Stromberg made a tool for removal of same, no lead seal is involved. The tool is like an easy out but smaller and it has fine threads.
I can send a picture if this is what you are talking about.

Yes thry are behind jets, John please send,I feel they need to come out for cleaning if I can do it without damaging.
Sorry John, but the only two times I have attempted to remove the Main Discharge tubes from Stromberg's I have found the remains of tiny lead seals that sit right at the top of the tube against the body before they enter the Venturi. In both cases, they have been pulled apart on removal. Perhaps fitted by some aftermarket re-builder firm, but what do I know?
Steve,
You don't have to be sorry, but here I thought you knew everything.
If you look it up the following applies:
1935 and 1936 Stromberg for LaSalle had (13) Main Discharge Jet P 20753
1935 and 1936 Stromberg for LaSalle had (75) Gasket Main Discharge Jet (lead) P20421
After that Stromberg did not have a Gasket Main Discharge Jet (lead) on any of the Cadillac or LaSalle Carburetors. You can see the design change if you compare the early LaSalle to a later Cad or LaSalle part.
But I have a few of these with the lead gaskets and they have come out easily. After those years I have not had a problem and not seen the lead gasket. I can supply pictures of the early LaSalle and the later LaSalle and Cadillac so you can see the difference in design.
It could be possible folks have used the early Main Discharge Jet in the later carbs, but that is just speculation on my part.

Giff,
Here is a picture of the tool.
It is made by the following folks;
Main Jet Remover
Stromberg T-24967
Snap On
MC-50A
Carter
T-109-178
Kent Moore
KMO-269-S-4

Thanks for the pictures John,do they come out easy?
Giff,
Easy is a relative term.
I usually soak the discharge jets in Kroil, for a day, before trying to pull them out, then stick them in Carb cleaner for a day or so. Then clean them in hot water and dry them with compressed air. Then, generally, they come out nicely.
One other method is to put the body with all the parts removed, after cleaning as above, into a sonic cleaner. These are the ones, for instance, used by dentists. They will clean the main discharge jets adequately without having to remove them.
I purchased my sonic tester for around $200.00 (thank you Art G.) and it works great. I usually clean the body in the Sonic tester more than once.
That is my story.

You may well have hit on something there John as I have never dismantled a pre 37 Carb, and shame on me if I give the impression I knew everything. Good to know I have seen the lead washers though and wasn't imagining it.
Steve,
I believe the American expression used often is that "I Was Pulling Your Leg".
The Johnny
Another explanation is that decades ago my carb parts bin consisted of many different parts of Stromberg's., mainly Buick as they were much more prolific here. The center section of the body from the Buick 320ci is virtually the same and when cleaning some of these center sections with the discharge tubes it's more than likely I used a Buick one. Could well be that Buick continued to use this washer type well after Cadillac ceased to? Having said all that and since being wary of removing the tubes I have found they can be cleaned without removal as John states.
Steve,
It looks like Buick used the lead gasket at least to 1952 in many of its Stromberg AA type carburetors.
The Johnny
That's the answer then John. I love it when you can learn something every day :)
Steve and all others,
One needs to pay attention to the Year and Application of your Stromberg Carburetor.
The parts look the same - BUT They AIN'T...
So tying to interchange parts (even tho they fit) can result in poor performance, bad gas mileage, or other problems.
Trust me on this I have experience is trying to interchange parts from one year Cad Stromberg to another with bad results.
