carter wcd 935s or 931sc

[Phr]

Hi  Mopar fans

 

Once again ? I would like your advice !

On my Chrysler New Yorker 1953  V8 Fluid drive I have a Carburetor carter wcd 935s. It was "rebuit" with appropriate kit, but after this winter, it works very bad (too rich and hard to tune up )

I have found a New one ( rare )  But it's a 931 SC !

someone know the difference between 935s and 931sc  and if 931sc will fit my NY 53 ?

 

Thanks a lot from Belgium

They are identical in fit.

Only differences I can find

SC has an inside vent 

S has only outside vents and one to the kickdown switch.cartersc.pdf

 

SC has a bit more economical metering rod. Could probably swap it since the orifice is the same.
