dumb question i know... but i am english...

[fatchap]

Just got a hongdou gy200... and trying to assemble it.

The carb has a pipe coming out of the bottom, with no clip on the other end of it, and i can't find anywhere that it should go to. I can see another pipe which feeds from the fuel tank to the carb input, but i'm not sure on this pipe from the bottom of carb...

Anyway, looked up one one of the schematics posted on this site, and its quoted as oil overflow pipe. Has anyone got a better description please of what it is, and where its supposed to go.

thanks!
