First let me say I AM an advocate of EBAY and had to learn the ropes due to to necessary. See, my jeep of choice (accident) is a 1956 DJ3A Fastback Convertible. A mostly despised by the real Willys Crowd 2 Wheel Drive odd little duck. Not only are they EXTREMLY odd, most venders don't even recognize them or carry replacement parts. Since mine was mostly stripped of about everything valuable I had to do a LOT of research and learn fast.
Even finding a correct carb was quite a ordeal for me. If you don't believe it, try looking for a Carter YF2392S or YF2392SA.
During my research and learning process it came to my attention to Buyer beware when it comes to eBay. During my studies I was often able to spot 'genuine' Carter YF Carbs advertised as older or long ago rebuilt carbs BUT especially on the 2392s carbs I've managed to identify multiples on these that were rebuilt using the wrong number throttle base.
Recently it came to my attention that not only that.....there are also advertised as NOS carbs on eBay that were made overseas that look decent but ARE NOT made to original Carter YF specifications.
It is being said by other experts in the field, including scout pilot, that these carburetors will NOT work as advertised.
Yes the ersatz 938's that recently appeared on the market could be considered fakes. However, other than the extremely poor quality of the alloys used to cast the accelerator pump housing, the top, bowl and throttle base, all of the parts inside, and the linkage outside are Genuine Carter. These were part of the very last, foreign-outsourced, low-bid, production run of 938SD's. QC was definitely lacking as Carter was in the throes of bankruptcy and a reorganization effort that eventually failed, resulting in their being rolled into Federal Mogul, another subsidiary of American Car Foundry (ACF). Federal Mogul continued the manufacture of parts and rebuild kits for a few years. Then the Carter Brand quietly faded. When these last ones appeared on the market, I was fortunate enough to encounter them through a reputable vendor who explained to me that these were definitely not going to work in their current state. Strictly parts only. I purchased eight of them from him ($25 each) and after their arrival I began to delve into them. Sure enough, the accelerator pump housing is trash metal. Every one of them, in every carb, was cracked from over-stress of weak amalgam. I experimented with replacement parts, but soon discovered that the major castings were sadly out of spec as well. The throttle bases were so poorly forged, they have voids where air bubbles had been trapped in the mold. The throttle shaft bores are over-dimension as well. So straight from the factory they require that bushings be installed. Know your vendor, know your purchase.
Even though we've never done business before I know your reputation is excellent and for that I applaud you. Taking the time to make the videos, answering questions and helping everybody; testing and warranting your work, going the extra mile, well that all speaks for itself. Standing ovation and good luck.
Besides that, I learned a new word!!
er·satz \ˈer-ˌsäts, -ˌzäts, er-ˈ; ˈər-ˌsats\ adjective : copied from something else and usually not as good as the original Full Definition :being a usually artificial and inferior substitute or imitation <ersatz turf> <ersatz intellectuals>
my 46cj2a came with a yf2392sa ran when bought it 2007. replaced the carb with a correct one. the yf has been sitting on a self in my basement since then. throttle base 1-648 I do not know if that is right or wrong but looks right. I do not have a use for it if interested let me know
