"I have a new 9.8 that I run regularly, and has been running good. I have noted that the top spark plug gets a lot dirtier than the bottom plug. Last time out I pulled the plug mid way thru the day and cleaned the plugs. It made a huge difference. Do these plugs need to be cleaned after each use?
What about running a hotter plug? I just went over the 10 hour break in and am about to change the oil and filter. Thanks for your advice."
