I just bought a 96 Yamaha Big Bear 350 4x4..It has been sitting for 5 years..I got it cranked up and even running...There is a fuel line on the top side of the carburetor that runs up toward the bottom of the fuel tank but is not connected to anything...Does anyone know where that connects to?? The fuel line on the bottom by the bowl is for the over flow. The fuel line that goes from the tank to the ON/OFF/RESERVE is hooked up...I just cant imagine there being two over flow lines...Please help.

That hose that is not hooked up is a vent and overflow.  The hose on the bottom is the float bowl drain not an overflow.  Bottom line is that hose should be long enough to be routed down under the machine.  It is not supposed to be connected to anything but it should be checked to make sure it doesn't get plugged with mud or dirt.  A tip for preventing a clogged vent hose is to split the first inch or so of the hose with a knife.

However being it has been sitting for so long it would benifit from a complete fuel system tear down and cleaning to ensure that debris from old fuel or storage won't clog a jet or passage while on the trail.
