Spark plug twisted off.

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.

That is a lot of work for a spark plug. Good ob on taking the time to get it out and do it right.

For the buildup on the valve; was it an intake valve or an exhaust valve? And how's the fuel quality where you live. If the fuel gets stale, it can result in a varnish buildup on the intake valves. And fuel additives or contaminants will often stick to the exhaust valves.
