i had my friend over today and we put in a new spark plug. The one i took out was kinda black (rich?) , but than again it was pretty old..

Anyway, that smaller screw was a drain screw i think, or at least that was what my friend said.

That is supposed to be screwed all the way in isn't it? and if it is, how is **** supposed to drain out lol

Thanks for your help so much I really appreciate it!!!
