I have a 2000 (?) Bear Tracker (YFM250XM). The hose (about 8" long) coming off the bottom of the carb has become disconnected. Gas simply runs through the hose onto the ground. But I cannot find what it is supposed to connect to.

Does anone know what this hose connects to, and were to look for it?

 

I think you are describing a float bowl drain hose. It is doing exactly what it is designed to do assuming you do not have the screw in place which is supposed to be screwed in.

 

Also if screw is tight then prolly needs carb. cleaned and replace float value.
