Hi Narutokun

There is a wealth of information on this site. Just use the search function and i'm sure you will find the answer to your question, if not many other answers too.

If that doesn't give satisfactory help, there are quite a few seriously switched on people cruising the forum.

Makes no difference, that you will be able to tell. Your plug is not seated causing fuel mix to escape around the threads. Head may not be threaded all the way, might not have a good finished where the plug seats. You can get a plug gasket/washer and try.
