This is a new carburetor for the 134L four cylinder flat head Engine. This is for replacing the old Carter WO. (once you rebuild it so many times the casting wears out) This will fit the MB, GPW, CJ2A, CJ3A, M38, Willys Truck, and Willys Wagon. This is a nice copy of a Solex carburetor which is not being produced any more. This will bolt right up to your intake manifold. Your air horn for the air cleaner will fit just fine as well as the accelerator linkage will match up. These are new fresh reproductions ready to install.  QTM Parts 

Note: Like all new carburetors you may have to do a little adjusting. 

For the M38 Application you will have to add the MB/CJ2A style air cleaner horn to work with your original air cleaner system.
