I could not determine what the factory had in mind for inserting the crankcase breather hose through that 1/4" hole above the drive sprocket, so I added a plastic 90° fitting to the end of the breather hose. The tapered pipe threads cinched nicely into the end of the hose, and the 1/4" barbs on the other end made a light press fit into the engine case.
