Solex carburetor issues on '46

   I am attaching the link which came up during my Advanced Search for Solex carburetor issues. And I am hoping these threads may be helpful for another individual who is also trying to learn about the Solex carburetor.

   The history is this:   My '46 which I purchased in Dec. 2017 does have a Solex carburetor with no markings on it. (I think it is Aftermarket).
   I have been diligently searching the net for information of where to get a rebuild kit because the accelerator lever was not depressing the pump diaphragm to squirt a charge of gas, nor would it idle, but die.
   This carb has the weirdest choke with no butterfly, but some rotating disc affair with a hole in it which must restrict some sort of air passage.

   Personally, I think I like Carter YO design better, and have had very good luck with the Carters on other older vehicles besides CJ2A's.
   I am learning as I go about the "differences" in these early jeeps now that I have one to rejuvenate from the pasture.

   Did the original fuel pump which fed the Solex only have 1.5 lbs pressure ?

And are these low-pressure fuel pumps available today, or do we need to purchase a pressure-regulator ?

   The information in the threads which popped up in my search was most helpful and it appears that many Solex owners are very happy with them.

   Is there a good link giving Solex adjustment settings ?
   I haven't done a web-search for Solex rebuild and tuning instructions.

   Where I am currently, is that I did find a rebuild kit for the Solex on the website for "cjjeepparts.com" and it appears that these Solex carb kits are made in China by OMIX. I don't recall finding a U.S. made kit.
   Standard may make a kit in the USA, but I am not that far in my search.
I think Standard brand is sold through Napa stores, and I haven't checked the Napa parts list which recently popped up.

   I really don't like how this Solex style carb mounts, but if i can get it to work smoothly, then i will run it once i get the gremlins shook out of it.
Currently, the engine won't idle and the accelerator pump diaphragm was petrified. Nor have I driven the jeep yet with the Carb issues not solved.

   Quadratec and Walck's both had the Omix carb kit for Solex also.
I am hoping i can purchase it from Napa locally, but had no luck when i called-in on the phone, so i will have to take the carb into the store.

   The threads i found in my search convinced me that the Solex may be worth trying to dial-in, and may help another individual wrestling with the Solex.

   My father would sometimes take a carburetor over the the Anvil and speak to it with the 8-lb splitting maul. He would do this after the 4-th attempt at a rebuild, and then smash it. Today, we need the old carb intact as a Core.

   I have not really had good luck buying rebuilt carbs in the past, so i am hoping to nurse my Solex back to good operating condition.

I too bought my CJ2A back in December 2017.  It had a brand new Solex on it.  It ran ok, but not great.  Last month I called Scout Pilot and ordered a completely restored, correct Carter WO for it.  I installed it a couple weeks ago.  The difference was dramatic. It runs SO much better than it did with the Solex. Starts right up, no hesitation, smooth, even power.  To me it it was worth every penny. You might want to consider doing the same thing and save yourself a lot of headaches.

I couldn't agree more with ndnchf, My 47' had a solex when I bought it. Ran fair, I installed the recommended regulator, not much change. I could adjust the solex and get it to run pretty good then the next time I drove the jeep it would be running rough again. I bought a carter on ebay just for the core, thinking I would have it rebuilt. I installed it, with no adjustments at all the jeep ran great. I think carter has to be the way to go.       

I mentioned on the other post about my Solex.  When I first put it on, my 2A ran great and I didn't need a pressure regulator.  It worked very well for years and then it didn't.  The Jeep was peppier with the Solex 17 or 18 years ago than it is now with the Carter back on.  I wish I knew why...

I am sure it has nothing to do with the 17 or 18 years. It must be the carburetor! You should get another Solex.
