Ok so that just happened yesterday! how I got that right is by simply not thinking.
Now I tried to remove it from the outside but it just would not work. I had to remove the entire topend.
After the top was removed the rest of the plug came out quite easy, simply slammed out the ceramic bit and softly hammered a Torx bit into the remaining part of the sparkplug.
one thing I noticed is that one of my valves had this crust of hard soot? carbon buildup? it was really hard but I chipped it off. it was very much like the carbon buildup inside a suppressor on a rifle :prob: now that tells me i am seriously running rich? I am kind of irritated with myself that I did not take more than 4 pictures.
