Better than expected

Buying a precision product from China is sometimes a gamble, but this one was better than expected. It was well-packaged and shipped with a tracking number. I was hoping to get a kit, but the engine came fully assembled. The crankshaft and connecting rod assembly would have required special tools. The enclosed documentation showed how to adjust the valve timing if necessary. Initially, the engine would only run on at least 3 kg of pressure. I lubricated it and ran it for about 3 hours off an air compressor. After that it ran smoothly using an aquarium pump. I use a Hygger HG-041 pump which is clean and quiet, so I can operate the engine on my desk.

4 cyl steam engine

Looks to be a nice engine, tolerances could be a bit tighter though. Slop in the drive gears.
