I have a 15 hp. sea king cg18802a 36x882787 does anybody know whats proper plug for it. It has 2 j6c plugs in it now. I have been told to go to a j8c because it runs hotter any suggestions. Also, what year and what oil/fuel ratio should it run.
Old thread. Please start a new one with new questions. You don't even have the same motor. But anyhow, J6 is correct. Do NOT use J8. Mix is 24:1, use TC-w3 oil and regular unleaded.
