Here's all I can find on it. From a 1955 Carter Carburetor manual (click to enlarge):

Could the 311 be a 377? If so... I might be interested in the carburetor if it has the Carter 'Carstarter' switch on it.

JD,

Thanks for identifying the 324 carb. It confirms what I thought --the application is a Buick.

The other one remains unsolved. I checked the number again--it is 311. A not so reliable source said the application was a teraplane.

If you know of anyone selling a 324 please let them know I am interested in buying one in rebuild condition.

Thanks

Rick

The "324" and the "311" do not positively identify either carburetor. These numbers give one a starting point. Note in the partial chart listed that there are five different carburetors with a stamp number of 524. The 311 is also Buick.

What are you trying to do?

Jon,

The one carb, WCD 324, has been on my 1940 Buick Special Series 40 since 2006 when I purchased the car. I have tried rebuilding it but the core is no good. I am looking for a replacement core to rebuild. According to one Buick parts supplier the carter WCD model is applicable for 1941 & 1942 single Carter 2bbl. The same supplier says the 1940 Buick application is a Carter WDO model.

The other carb , WDO 311, was recently purchased from a person on this forum. He said he took it off a 1940 Buick Super. It is a good core however when I tried purchasing a rebuild kit the Buick parts supplier said it was for a 1932-1936 Teraplane. Hence the reason I posted a help request.

Do you have a good carb core for a 1940 Buick Special Series 40?

Thanks

Rick

Rick, a little information:

First, the numbers given are NOT identification numbers, they are CODE numbers. The stamped number was stamped to help Carter distributors identify carburetors which had been through commercial rebuilders that threw away the tags.

Second, the 311 CODE number is different from the 311s IDENTIFICATION number. A Carter 311s was definately used on a 1935 Terraplane.

The model "WCD" is NOT unique. There were many different type WCD carburetors.

There were four different (2 Carter and 2 Stromberg) carburetors which Buick installed on the 1940 Buick series 40. We can probably help you with at least one of them. (573) 392-7378 (9-4 Mon-Wed central time).

Thanks for the information.

I took a closer look at WCD. The three numbers ,311, are stamped on the very bottom at the ports. There is no letter " s". At the top side near intake is s349. On the black plastic choke cover 170G64S. Really want to ID this carb so I can get correct rebuild kit or sell it if not for a 40 Buick.

Thanks

My Carter book shows a 440s for 1940 "40" motor 43671415 to 43672299, 43672642 & higher with casting number 225 on face of flange. 440s was later superceeded by 474s (Carter form 4582F dated Jan 1940 reprinted June 1946). My guess would be that the other motor numbers received a Stromberg.

Also found the 474s was used on 1940 "40" and "50" motors (4?)3976130 to (4?)3984999 and (4?)3990175 & higher (hope these motor numbers make sense to someone) as well as superceeding the 440s (the (4)s are not on the Carter sheet for the 474s but were on the 440s)

The 474s casting number was 311 & looks like the 440s had a gray choke cover and the 474s, black (170g-64s). The 474s Carter sheet is dated April 1940.

ps looks like the 419s was the same carb in 1939.
