Hello all!

I removed the sparkplug yesterday and I have some trouble the determine the health of my engine.. Can someone help to read My spark plug?
I have read that it should be pretty brown, but where do I read?

The Threads are � bit black, but the "bended" metal are Brown.. The ceramics are pretty white.. I don't know where to look?





If something is wrong, too hot or too cold, how can i setup the engine?

Thanks in advance!
