We have rebuild kits for them now. Email mike@kaiserwillys.com for help if you need one.

Is this a better option than the soles style? I am not having much luck with my solex. Does the fuel pressure need to be reduced with this one?
Willys Jeep Parts Tech:
Just need to have proper fuel pressure in general for either to work. Both are good honestly. Email mike@kaiserwillys.com to help.

Hi Mike I have researched the catalog to see 2 carburetor options for’62 F134 Hurricane. Please advise on Solex 923808 option. While watching your video just now I am very interested in the rebuild/refurbished option by KW of my existing carburetor. Is there a means to easily identify whether my existing is original and worth the effort?? Thanks Ric Gerttula 503-791-3535

I haven't found where I can provide feedback, but wanted to tell you that this carb works great. I have struggled with the solex carb for a couple of years and could never get rid of a flat spot on acceleration. I have more power and a good running engine with this one. Thanks - just wish I would have bought it sooner.
Willys Jeep Parts Tech:
Awesome to hear!!!

Where is this made? Can you get rebuild kits for it? Will it work with an electric fuel pump? Do you sell the dry element air filter for it? What is outside diameter of the neck, where air filter slides on? I have a YF964 on my F-Head, which is "too much carb" for it. But it has a slide on dry-element air filter i would like to use. (ALSO, i have a CJ3A, so there's an existing hood bump this carb would need to fit under!) thanks!

If you can please email mike@kaiserwillys.com and we can help answer all of this.

Why is this recommended with a dry filter element instead of the factory oil bath filter? Also is this recommended over the slightly cheaper show quality YF you sell? Last, where is this manufactured?
Willys Jeep Parts Tech:
You could use either. But a dry functions a bit better than the original oil bath. I'll check on origin.

Will this fit my 1964 CJ5 with F134 Engine? Also can you measure & tell me the mounting bolts holes location, so i can see if they will line up. I just bought a Omix from Quadratec & the holes were 0.25" off center.

Yes, this is 100% correct for the CJ-5 with the 4-143 F Motor.

Is this designed to be a direct replacement for the Carter YF-938 or will there be modifications to fuel line, choke and throttle cables required? I am interested in giving this one a try but would like to not have to make any modifications in case I later decide to go back to my Carter.
Willys Jeep Parts Tech:
Yes it is a direct fit. You can see our install guide too above.
