I need to know where these 3 hoses go to from the carb. they are labeld A,B and C. Also can anyone tell me where i can get the sprocket nut. This is a baja wilderness 250 2004?

Thanks

 

b= vent tube, goes to nothing
c= drain/ overflow and it goes to nothing

 

wow you mean they just hang there like that? how about the sprocket nut? is it reverse threads and where do i get one? thank you also on the carb, there is a line going to the petcock on the other side of the carb so where does line A go? thanks
