I bought a 134 F- head engine that came out of a 57 cj3b. It had a Carter yf 2392sd carburetor on it that the seller told me he had rebuilt but it still would not run properly. Someone said that this carburetor was designed to be run on the dj3a L-head engine. Any thoughts?

Iím not really familiar with F-head engines so I canít help you much there.

Willys DJ3Aís l-head motors used Carter Carb YF 2392S until they later changed the Carb number to YF 2392SA. The ending letter change from S to SA was likely due to going from a air bypass check ball to become an air bypass check needle but I havenít personally checked to confirm.

Hereís a link to various factory specifications and application of these mentioned and of other Carter YF carburetors.

If I understand the bulletin on the Carter 2392 sa carburetor, it may need a Carter field fix kit no.920339 installed to stop surging problems that may occur when run on the F-Head 134 engine which has a water heated intake manifold.

Hereís a link to the actual bulletin that you referenced.

http://www.jeepsurreygala.com/wp-content/uploads/2012/05/WO-Service-Bulletin-446-YF-951S-Carb-Surge4.jpg


That says that the Carter field fix kit no.92033 is specifically in reference to a Carter YF 951S. YF 951ís are listed for Willys SW, SD, 4WD TR- 2WD TR & Utility Wagon, Utility Sedan, Maverick 1952-1960.

The carburetor listed for CJ3Bís etc F heads is Carter YF 938 series.


Sorry that I canít be more help but I donít see any mention of kit no. 92033 applying to a DJ3A l-head YF 2392 series carburetor.

Yes. That link does contain information about all of those various carbs:Willys YF Carter Carburetor Specifications 938, 951, 2467, 2392, Solex M 34 PBIC (YF), Solex M 32 PBIC (L head)

All in the way of application, forms and a dealer service bulletin titled ĎTO ALL DEALERS, DISTRIBUTERS and REGIONS: SUBJECT YF 951 CARBURETORS SURGE.í

Each separate dealer bulletin and form from this link is clickable to a new screen in and unto itself and contains specific individual information concerning each of these carburetors.

I have a Yf2392s disassembled right now and a YF2932SA on my 63 dj3a. Charles helped me find the SA on Ebay. I will say, it still lagged a bit but it certainly runs a lot better than the original S. If anyone needs pictures to see differences I'd be glad to help.
