"Retro 50" carburetor ID help

[brendans]

Hi there,

I've googled my everloving a** off trying to find information on this machine (a craigslist "it'll need a little work" find.)

The owners manual calls it a "Retro 50" distributed by Madami. The model is listed as a "CF50QT-8" (I believe this refers to CF Moto.)

The trouble I'm finding is related to the carburetor - it's a Walbro that isn't manufactured anymore. The model stamped on the carb flange is 2KO6JG2 (the O could also be a 0 (zero.))

Is anybody familiar with a drop-in replacement? I could potentially rebuild this one, but the float bowl o-ring broke and I'm not even sure it could be replaced.

One thing stumping me is what appears to be a passthrough on the front (intake manifold) side of the carb. It runs horizontally and had two braid-covered hoses connecting to it. But it doesn't appear that the passthrough allows access into the carb - it's just a connector of sorts.

Anyway, I'm rambling. Any help would be appreciated!
