Swapped the sparkplug for a shiny new one :)
(Preview)
As title, but I want to know was the old plug looking alright. I know you can tell a lot from how the spark plug looks.. So I took a few pictures. Also I don't have a torque wrench so just tightened it by hand and then put a half turn on it with a normal wrench. [IMG]https://i3.photobucket.com/albums/y60/s...
