Anyone ever heard of these? There are a pair for sale here in town. Description is:

Pair of rare 45mm OER SR Japanese race carbs, DCOE pattern. Cleaned and refurbished by previous owner. Good use for Toyota, Datsun, or VW 4 cylinder applications.

SK possibly? Japanese weber copy. If they are fairly inexpensive, you might grab them, they are well made and will probably work well depending on the application. Some, but not all parts should interchange with weber, although some early SK versions may not. Our weber linkage will probably work with them for U20. I would not try to use them on a 1600.

Basically they are a hybrid - think a mikuni redesigned to use Weber DCOE parts. Not much specific aftermarket support, but they supposedly work better than Webers.

Yep, they are pretty nice and high quality. If you can't afford Mikuni's these are a good choice.

Use caution, parts are only available from Japan. They have no US distributors and a gasket kit for one carburetor is over $100.00 last I checked. They are a good carburetor but they are not supported in the United States.

I ran a new set of 45mm OERs before my Dellortos. They were excellent, well made carbs, made in Japan and we're a hybrid of Mikuni and Weber. I don't recall what parts were interchanged, but I do remember it used the Weber DCOE style of accelerator pump system, which seemed less prone to plugging and made the carbs easier to mount. Linkage should interchange. Should be able to use Weber or Mikuni jets once you figure out what they are using.

Those shown may be different from what in had. I do see a port for vacuum advance, which would be nice.
