I picked up a 2004 660 grizzly that had not been started in about 18 months. Since it idled rough I took apart carb and gave it a good cleaning. My question is, when putting it back on quad there is 1 hose that comes off the left upper part of the carb that comes to a T. Were do theese 2 hoses go(if anywere) or are they just vents? On the other side of the carb there is a rubber cap covering that hole. Thanks.

 

Id think they are vents.
I sent a pm

 

The two holes on top are the vents. One end has a black rubber cap. I put a tee in and tied both of them in to the vent line.
