I have a Sea King 15 hp by chrysler<br />model # VWB 52119A serial # D8X21987<br /><br />The motor works pretty good, I have had it for a couple of seasons, but I need to find a service manual so I can keep it in good shape. I also need a pull start assembly,(I have to wind the rope by hand each time to start)and I would like to know what year, oil/fuel mixture, and spark plugs to use. I run it 50:1. <br />any help would be appreciated.<br />Thanks, Frank
