Why do I say it's a kit when it comes assembled? Because it needs a little work to get the best from it. Includes holding the cylinders in place with silicone sealer rather than the screws provided (which distort the cylinder bore.) Also you'll need to add more heatsinks if you want long stable runs and don't be afraid to tweak and tune timing and replace the cloth wiicks with fibreglass. I fully disassembled and reassembled after work with a flat-cut finishing file and taking care to eliminate friction.
To start the engine, preheat with a hair dryer; when finished, rotate the engine a good few times by hand to get any meths condensate steam out of the cylinders or they will rust and stick. Only use graphite dust for lubrication, I have an older video of tweaks and work on my channel Thomas PCGuru Engines
Alles okay super
Very cool little working model . Well made and functions very nicely. My elderly dad loves it.
