• Spark ignition engine.
• An ideal first project.
• Easy to construct (basic engineering knowledge required).
• A fascinating engine to build and watch.
• Can be built on a 3½" lathe.
• Kit includes 8 high quality castings and drawings

The original engine was one of the first engines constructed by Gottlieb Daimler and used in a very early motor carriage "The Motorkutsche". This engine was called the "Standuhr". It was the first "fasr running" petrol engine ie it ran at about 700 rpm.

Unusual in this engine is the method of valve operation, a disc with grooves in place of the more familiar cam.

Supplied as castings and drawings for home machining
