Just as the Title says... my 2001 Merc Carb. 115HP has been running very ugly, very tough to start. I am the only person who can start it now because I know the 'tricks' on how to do it. I finally thought my troubles starting and running could be old and dirty spark plugs. I took the plugs out today and noticed they were very dirty and very oily. In fact, there is visible oil deposits coming out of the cylinders through the sparks plug holes. not much, but very visible amounts. # 1 Will replacing the plugs help my starting issues? #2 Are those oil deposits normal in my cylinders? #3 could replacing the plugs help the overall smoothness of the motor?
