Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Hi All,
I have never had a hot air engine before and I have bought an old Carette engine. I'm just checking it over at the moment and I wanted to give it a good clean. My question is, should both pistons simply pull out once I have unscrewed the securing screws? The cap for the bigger piston has been soldered on and I don't thing this is how it should be. I'll take a photo shortly.

tried to add a photo but it says upload folder is full? I reduced the photo size by 75% still says it

Please post pictures.
