Default Onan W2S, Carburetor Needed

Hello,

I purchased a W2S from a salvage yard for 15 cents a pound about 3 years ago. Took it home, added gas, oil, antifreeze and a battery... It started upon the first press of the start button and runs awesome. It effortlessly produces 120V under load. I can easily start her by hand crank also. It has a dual set of coils and points for ignition. Unfortunately, she has a modified intake to adapt an updraft B&S carburetor.

S/N 72.39399 (mnfctr. 7/1942)

As I approach time this winter to restore her, I now need to locate an original carburetor. The previous owner installed an old BRIGGS AND STRATTON Flo-Jet ‘updraft’ Carburetor #390323. I believe the original carb was a Zenith. Any help is appreciated to restore her back to the original carb or at least a carb that will perform better than this old B&S.

Thank you Kindly,

Dave

Sorry I don't have a spare, but here's a few pics of what you're looking for... These are awesome old machines and tough as nails. I pulled my cylinder head to repair it but found I need to sleeve a rusty bore good luck with yours and post some pics!

Thanks Andrew!

I will post pictures when I get home today. I enjoy this little genset and want to see it completely restored. You wouldn't happen to know the model number that carburetor would you?

Additionally, I would like to install new brushes on this generator. If anybody has information on the size of brushes for this that would be greatly appreciated also.

12160D or 12160B seems to be the Onan part number mine is a little buried (I'm moving equipment innashop today, building the Onan a new home). Once I roll it out I'll see if there's a number on the carb itself.


Also nice job keeping yours from the scrap man!

she is a beauty and complete! That would make a nice project to totally rebuild and a nice new paint job to match factory OEM paint. Afterwards, it would make a nice center piece in the middle of the living room, but my "boss" would kick my azzz if I did that.

It is complete with the exception of the carb, which sticks out the left side like a sore thumb and which needs an air filter.

The two original 6volt parallel ignition coils are still functional, but the spark appeared weak, so I installed a small dual wiŕe motorcycle coil inside the cast coil holder this week. She starts quicker because of the hotter spark now. The plug wires are too long from the m/c coil and that is the reason why the plug wires are crossing over each other, they will be shortened later.

Are there any suggestions at all on a different type carburetor that can be installed on this engine? I can make an adapter for a horizontal carb and get rid of that obtrusive updraft carb. Just want to know of a good reputable carb. The salvage yard that sold me the carb has literally stock piles of old gas engines of all makes and models, including tons of late model Onans. Again, any carb recommendation with experience is needed and valued.
Much appreciated, Dave

I have some of these units with up-draft, down-draft and side-draft. Yours originally used the up-draft carb. The remains of the air cleaner and choke in your pictures show this.
There is one carb that they used on these that will adapt from up to down to side draft just by repositioning the bowl. I have one of these available, but it is not in the best shape. Complete, but stuck from sitting outside a long time. Could be usable with some effort.
Here is a picture of what your carb set-up should look like.

I am very interested in the carburetor that you have available that you feel will work on my generator. How best can we make arrangements for the purchase thereof?

Much appreciated!!!
Dave
