2004 Yanaha F60 non-EFI model Sort of a strange problem, but here goes. Changed the oil (10W-30) yesterday, old oil came out black and smelling like gas. ( I troll a lot with it) after adding the fresh oil and running it up for 5 mins the dipstick showed oil slightly milky. Checked all 4 spark plugs and they weren't washed.
Any idea's
Thank you
