Well, after more research into this carb, I found out it is a Holley 5200 series. This carb, it turns out, is a popular upgrade for the Mazda B2000/2200 and the Datsun 1200 motor. The Holley 5200 is a licensed Holley clone of a Weber 32/36 built for Ford for the mid to late '70's Mustang II, Ranger and other models. Hmmmm, I thought. So I bought a Weber adapter plate for the Samurai and it fit! I then made a throttle cable mounting plate, found a 3/16" hose barb fitting that fit into the fuel intake port on the carb (it normally takes a screw in filter but the fuel fitting was too big), plugged a bunch of vacuum lines and fired it up. It runs great!
I haven't taken it out on the road, yet, because I haven't got an air cleaner on it. I think the air cleaner box for a Weber 32/36 should fit nearly perfect.
The engine ran a little rough at idle with the distributor vacuum advance plugged into manifold vacuum so I changed it to ported vacuum and it idles much smoother. Once I get the air filter assembly, I will road test it and work out any kinks. My initial feeling is that you can add this carb to the list of alternative carbs to upgrade the Samurai.
Seems like I scored pretty well with this "Ebay mistake".
