Kawasaki fr691v carb question

It should be the Crankcase vent hose and vent the crankcase into the air cleaner so the engine can try to burn the blow by gases. It wasn't there these raw gases would vented to the atmosphere creating more pollution besides it helps the engine to be more fuel saving.

Ok thank you for answering now i have a few more questions
If there was moisture in my crankcase would this hose vent moisture into my carb causing ir to ice in cold temps? I have found ice in this hose along with inside my carb and a white milky substance on the inside of my dipstick sleeve

Carb icing can occur at any temperature. It all depends on the amount of moist, air temp, and amount of pressure drop at carburetor. Personally I had a carburetor to ice over on the Piper Tomahawk plane I was flying at 90 F but normally it occurs the closer you get to the freezing point. Good thing they provide a way to heat the air before it enters the carburetor when this occurs or more planes would be crashing.
 
To answer your question yes sounds like you got excessive moisture in the crankcase and it freezes in the vent line as it is vacuum line which lower the air pressure. As water or fuel vaporizes it has a cooling effect.
 
One solution if you must operate in low temps is to provide some heat off the muffler to heat the intake air before it enters the carburetor. Many snowblower engines have this as a standard feature. But I think due the design of the air cleaner on this engine it going be a difficult to do. Talk to Kawasaki engine dealer to see if they have a solution.
