Questions: I have this Solex carb on an M-38 with a L-134. Since it was new, it seems to lose the fuel in the reservoir after it sits, even for a short time, and needs to be primed. This involves carrying a gas can, unstrapping the windshield, raising it, unlatching the hood, raising it, removing the air horn from the carb and dumping gas down it. The priming has to be repeated several times depending upon how long it has been sitting, until the bowl fills up and it continues to run. Then, everything has to be put back. After it clears out the excess gas from priming, it runs great, although it always needs some choke. Is there a way to remedy this, or to add a primer like aircraft use, which can be operated from the driver's seat?
Question By: John Allen on Sep 13 2018 3:49 AM
I would make sure you are pumping your pedal a bit before starting and during start up as well. Not enough to flood but get motor running. You will always need to choke a cold engine.

If you have the F head its unoriginal and would want the 923808 - the CJ2A used the L head originally and the 923806 would be the one for you.

Questions: i purchased the solex carb for my 1946 willys cj2a. i installed it and it ran fine everything worked as it should. After 12 hours there is no fuel left in the carb. i cannot figure out what the problem is. I have taken it to four professional mechanics and a local who worked on these while in the military and all of which say it has been hooked up correctly. So i had kaiser willys send me a replacement thinking it was a faulty carb but after installing the second one I am now facing the same problem. I cannot figure out what the problem is. I have put a new fuel pump in and i am getting plenty of pressure from it.

Questions: I have a CJ-3A that is backfiring and dying. If I keep the engine revved it stays running but you can feel the occasional bump of an almost-backfire. Distributor was replaced by a mechanic about 3 yrs ago, replaced the spark plugs yesterday. Tried adjusting the carb and while it helped the roughness of the revved engine, as soon as you let off the gas it backfires and dies. Was running fine until about a month ago. I am no mechanic, learning all this as I go. Suggestions?
Question By: Anonymous on Jun 11 2014 12:00 AM
I could be a fuel delivery problem. You may want to check your float. I would also try advancing the timing to see if that does the trick as well.

Questions: Hello, I have been looking for a replacement carburetor for a 4-134 in a 53 cj3b which has a 57 under carrage. I have a clearance problem, The carb which was on it was a holly and it drowned the engine, I have 6.5 between the manifold and the hood. I tryed the other Solex and it was too tall, The holly with the air horn is 6.25 tall, does the riser come off this Solex carb? Would it work?
Question By: Randy on Feb 27 2014 12:00 AM

Answer By: Willys Tech on Nov 5 2013 12:00 AM
Questions: Mike, both the linked docs here and various boards recommend installation of an inline fuel pressure regulator, delivering between 1-3/4 and 2 pounds of fuel pressure. On installation of the Solex on my L134, the mixture doesn't seem to be able to be leaned properly - it always runs too rich.
Question By: Sean on Jan 1 1970 12:00 AM

Questions: My 1945 GPW did not come with a carb., it was missing. I purchased a Solex from you and need to know how to choke it. Does the lever go up or down to choke. I don't see a flap inside and can't see what its doing.
Question By: keith on Feb 17 2013 12:00 AM
You just hook your choke cable up to the bracket and thats pretty much it. The function is internal on it.
