Love that Doll! You have it looking good. Hopefully it will run as good as it looks. My 365/1 has plenty of wear and is sluggish as a result.
One question. Is the cap on the right valve rod upside down? When I got my engine, the valve rod caps were oriented just like your picture. When I reassembled the engine, I oriented both caps so the center guide screws in the caps are 180° opposite of the valve rods. That orientation makes sense to me, but since I had nothing to compare to I could very well be wrong here.
Happy Steaming!
