The correct DJ carburetor is fully dependant on carburetor identification. MODEL IDENTIFICATION The "model designation number" is stamped sideways upon a thin reinforcing web at side of the fuel well body. The only correct carburetor for the DJ is the Carter YF 2392 S. That said it is certainly possible that some have installed other similar substitute carburetors that were taken from other Jeeps. The identification of a carburetor is compounded by the fact that carburetors may possibly be assembled from various similar models. WARNING: Swapping parts from one model of the YF series to another can be a huge mistake. Orfice restrictions generally are calbrated independantly for each and every model of YF. The specifications for the 2392 S are not identical to the more commonly found Jeep YF carburetors. That implies differences such as the main metering jets, the metering rods etc. The list of YF differences continues. I'm not certain whether or not I still have the original 2392 S specifications sheets. I likely sold those particular Carter publoications. I'll look for them if need be. |

Thanks Ken. Under those circumstances I now realize that mine are the wrong carburetors. I was planning a rebuild for it but after cleaning I realized it might have been a pretty rough candidate for a rebuild. If it had been correct I'd probably have gone to the ends of the earth to refresh but obviously now that's no longer an issue. Especially with the at least not entirely outrageous costs of other, similar, yf carbs. Luckily it was at least working so I may have to use it as is for a while until I can do better or closer to original. If you have access to the original specifications it would be nice to see them documented here if they aren't too hard to find.;) The next obvious question would have to be and I wouldn't have a clue how to go about this, especially at this time, what would be a reasonable substitute if there is one for the 2392 S original Carter YF carburetor? Thanks Charles |

Ok, after thinking about where I might have seen carbureator specifications before I went back and did some searching. The specifications for the DJ's correct CARTER YF 2392S can of course be found here at JeepSurreyGala.com. Also there are specifications for other YF carburetors (non-Dj) http://www.jeepsurreygala.com/?page_id=979 |

Yes Charles that's correct. Carter form numbers 5170 and 5170-D I haven't look into the best substitute Carter for DJ applications. But what you have may be as good as any. The Carter 832 SB was standard on post 1950 Willys Station wagons equipped with the F-134 Hurricane engine. |

Soooo. I finally break down and call Mr. Wallack. Good news was he had a yf 2392s, maybe a couple of them, rebuilt and ready to go and my pulse rate went up. Bad news is....NOT FOR SALE....without a core. OUCH....!!! He did give me Mr Sheets number and he's looking and will get back to me. Edit. Just called me back, no luck. Gave me Shelly's number from 'the jeepster man' calling now. Edit again. Shelly's looking, said she'll call me back. |

Update. I got a call today from another person (vendor) who was on his way home but thinks he may have one and IF so has made a solid offer (reasonable) of having it rebuilt to original specs and recoated to new condition. Should know for sure tomorrow so keeping my fingers crossed. |

Still don't have a carb, but I was given a heads up with new information concerning Dj carbs. Here's a post from 2011 and I felt this information should be added to this thread.
That being said, I'm not giving up yet looking for a YF 2392s ![]() Special thanks to ba for the heads up and additional information for a suitable carter substitute should it become necessary. Charles |

Ok. My carbureator problem is solved. A guy named Wally over at TONKA JEEP LIMITED, sales@tonkajeepltd.com http://tonkajeepltd.com/ Has made a deal with me got a carter yf, 2392s And I am giving him a plug here just like I have for everyone else on these sites that's helped me. First he responded to my one of my ads and , he'll accept a cj3b core I'v no use for (it's a old core) in exchange. After being turned down once elsewhere by another vender because of a CORRECT core (and don't get me wrong, I understand he didn't want to sell either one of his last two without being able to restock. I chose to think it that way anyway, any other way well, you know. Anyway we discussed on the phone and emails and he said he'd have it rebuilt any way I wanted to like or better than factory new condition in every way. Anyway, thanks Wally for working with me!!! Charles Ps Will post pics later on when it arrives. |

Wow. Shelly also came through and found a yf 2392 carb that would be suitable for a core. At a price that I couldn't afford to pass and I'll need it if. I ever get around to building my spare motor. She says that exact number carb was used on 'some' later model station wagons, and that's probably why she had that one stashed away somewhere. I wish i'd been paying more attention to the years she mentioned on the wagons but I do remember her saying it was on the ones with the smaller engines. |

Question. The base of this YF 2392s core carbureator is heavily pitted on both flanges and especially concerning to me are these rust pits near the adjusting needle orfice on the inside. They're deeper than they look it's not just stains, it's actual pitting.![]() As seen I can hand machine the flanges using a long piece of emery cloth, a dead level flat surface, and some elbow grease. However if these pits near the needle are going to cause problems there's no need to go any farther. Are there options that will work such as filling then...... machining them out by increasing the bore size and adding a slightly larger diameter butterfly....leaving them alone..... or do these imperfections make this a permanent parts carburetor. Thanks Charles |

As you say the base of the mounting flange can readily be filed or sanded down to become a flat surface. Pic was taken with poor lighting I suppose. I can barely see the pitted area in question. Regardless.... Absolutely do not re-size or re-bore the throttle bore area. Do not remove the throttle plate. Pits in the throttle bore will be acceptable only if they are not excessively deep. Let's roughly assume 1/16" as absolute maximum pitted depth realizing that deep and or abundant pits will produce flow turbulence. The throttle bore pits will be acceptable if they do not interfere in close proximity of the idle port.. Lets roughly assume absolutely no pits allowed within 1/4" distant of the slotted idle air bleed port. I'm basically stating that the air flow must must not encounter abnormal turbulance as the slowly opened throttle plate moves along the slot of the idle port air bleed. I have no direct experience nor any documented reference; so the above is only my opinion. It may be worth the effort to go ahead and rebuild the carburetor just to see if the pits effect its normal performance. |

Ken, thanks for the extensive write up and explanation of what is actually going on inside this throttle bore. It definately adds to my knowledge of what's going on there and what not to do. Number one is uncessary or detrimental material removal while cleaning. Except for sanding the flanges smooth I'v tried to be VERY careful about this and using very gentle methods throughout the entire carb and it's pieces. Unfortunately I had already removed the throttle plate before posting as it too was heavily pitted, especially around the edges and I have another out of the 832sb station wagon carb that is not pitted at all. It's a very slightly larger diameter and I was hoping to gently resize it to fit. Now I'm hoping that 'this' was not a catastrophic mistake in and of itself. The pittings in the bore probably are less than the 1/16 inches you mentioned but to the finger have a rough feel up and down that side. I haven't yet re-examined to see exactly how close any of the individual pits are to the idle port or the air bleed port so that's still a concern until I examine more closely. I did read a article posted on the .jalopyjournal that indicated this was a fairly common problem on older carbs which suggested carefully filling and smoothing out the pits with JB weld. With nothing to lose, and especially considering I had already prematurely removed the rusted throttle plate due to my lack of knowledge I will likely try the JB weld suggestion and smooth out the pits. |

I am a welder by trade; so my concern with the "JB Weld" is as follows. I have never used the product. One should understand that it is not a "weld". A weld may only be created via molecular fusion. JB Weld is a 2K epoxy that bonds via adhesion. The JB adhesive bond will be fully exposed to the gasoline solvent. If the adhesion is in any way incomplete, then epoxy particles could be sucked in by the engine. |
