Don't forget the pilot screw circuit. There's a spring, washer and o-ring at the bottom. Be careful not to lose them. Gently seat the pilot screw and count the number of turns it takes to seat. Then you know where to set it when reinstalling.

To remove the plug, I drilled a small hole and used a pick to pop it loose. Don't go too deep or you may hit the pilot screw itself.
