what subaru carb is this?

i still havent found any leads on what type of carb this mikuni is.its original equipment on a subaru vivio 660cc engine EN07 block.

carb has 33HDVT stamped on it.underneath is -720 8329 number punched. any idea if subaru used this engine or carb on other cars/bikes or boats (yamaha/suzuki?) maybe i can find info on this mikuni carb there

thanks
