Went out to check the oil before I plowed again and noticed a 14" long 1/4"ID black hose, appears to be a vacuum line type. one end was running down the right side of the engine and the other was laying under the carb. Only thing I can find is a small nipple on the bottom of the float bowl. Does it go onto this nipple, or is there something I'm missing?
I believe it does. I think it is the carb float drain tube. On mine one end is connected to the bottom of the carb and the other end hangs down on the belt side of the engine. I stuck a one way check valve in the bottom of mine just so it would never suck up muddy water.
