The owners manual does not address this. Is this a problem? Is a repair necessary? Are the parts available?   Also how much and what kind of oil should I add to the gas?   Thanks abledog View Member ProfileSend EmailFind Member's Threads Find Member's Posts mikeb Registered: 10/12/06 Posts: 3      10/12/06 at 06:50 PM Reply with quote #2 milky means its getting water/moisture in the lower unit you need to replace the the seals.
