The engine worked wonderfully right out of the box! A,few suggestions though. Make the cap that is removed the fill the pump larger. It is hard for aged fingers(75) to handle. Perhaps a t handle.
Also, make the gas control more sensitive. It seems like it is either on or off.
Again, a great little machine and would buy it again. Thank you.

fine little engine
Coming out of the carton, i noticed, that the return flow from the cylinder to the watertank was not attached and the two very tiny srews are missing!!! With a magnifying glass i found one in an edge of the wooden base and the other between the groundfoam and the carton. I do not understand why these tiny screws are not packed in a little plastic bag?! I had so much luck, because the Austrian customs opened the carton upsidedown! I had to tighten up most of the srews! The rubber tube between the gastank and the tuyere is very poor quality and i had to replace it. After all this problems, the engine works very fine and i am very satisfied!
