400EX Carb Tubes

[nlnieme]

I recently cleaned the carb in my 400EX for the first time. The process went well. However when I reattached the rubber tubing from the carb, I noticed I forgot where the small tube attached to the bottom of the carb went to. The tube attaches on the rear side of the carb and is next to the yellow choke lever.

Is this just an overflow tube? If not where does it need to be attached to?

Also the ATV runs fine.

Thanks.

Yeah that's just a float bowl overflow hose.
