compressed air engine

It's a compact air motor featuring rotary valves, boasting two pistons that drive its operation. To bring this engine together, certain adjustments must be made to the sandpaper lining the cylinders and any areas where parts don't fit properly, allowing for seamless assembly. Additionally, lubricate it with a non-hydrocarbon grease to ensure smooth performance. I strongly recommend securing the cylinders to your engine block using a reliable adhesive.
