56 Lincoln "teapot" carb.

Well-known member
I usually hang out on the Ford Barn sites for engines without valve covers. This is my first time on this section.
A friend owns a 1956 with a 4 bbl "tea pot" carburetor. He has had the carb re-built several times by supposed experts and no one can get it to stop leaking. From what I understand this style of carb has been a problem child. I have been telling him to replace the carb with an Edlebrock carb. He has spent more on re-builds that a new Edlebrock. My question is: How many CFM should he get? Thanks for any help.

Yes, the teapot carbs can leak and be temperamental in the wrong hands. They aren't a bad carb when they're done right. If you can edit/add the word 'teapot' into this thread title you may get more responses from those in-the-know folks here.

A 'Lincoln' y-block is effectively a completely different engine than a 'Ford' y-block. That's about the extent of my Lincoln knowledge. https://en.wikipedia.org/wiki/Lincoln_Y-block_V8_engine

*IF* the '55, '56 & '57 Lincolns were built similar to the '55 to '57 Fords, the carburetors & distributors are 'each year specific' and not interchangeable with those parts from the other two years.
'56 and earlier distributors won't work with '57 & later model carburetors.

The '55 & '56 teapot carbs have a smaller bolt pattern than the '57 & later so a carb/manifold adapter will be needed, plus a distributor.
IF the '57 Lincolns use a different distributor than the '57 & newer y-block 'Ford's, can you/he find a '57 Lincoln distributor for the 368?
While you/he are looking for parts, a '57 Lincoln intake manifold that hopefully fits the '56 engine, may have the larger carb bolt pattern and improved air-flow to match a newer carburetor.

Does the car have the 368 engine? Here's a CFM calculator.... something in the neighborhood of 450/500 cfm with a vacuum secondary would probably work fine, if the distributor compatibility problem is solved.

1937pickup, If you're friend is interested in keeping the original carburetor (teapot), I'm sure I can help him out. As dmsfrr was saying, because of the Loadomatic spark advance system in 1956, it sets off a chain reaction of things to purchase and change, like the distributor and carb adaptor etc.
I have a lot of experience with the teapot Holley's and have been doing them since the late 60's.

Thanks dmsfrr for the suggestion on adding to the post title. scicala, I will talk to my friend about trying another rebuild, thanks for the info and offers, both of you.
 
Fuel leaks on Teapots typically originate in two places assuming the carb itself is not flooding. One is the screw cover that covers the needle and seat assembly while the other is the fuel transfer tube with the two O rings on it. That tube connects the main body to the overhead fuel reservoir and like the aforementioned needle and seat cover, is exposed to constant fuel pressure for awhile after the engine has been shut down. The key here is to isolate exactly where the fuel is leaking and then address that area specifically.
