This is my latest build A frame four stroke diesel model. After several experiments with an arrangement I made, that makes it possible to adjust the injection timing when the engine is running, I am now able to start the engine from cold by hand. The engine is build 2012. Bore-Stroke: 20-40. Compression ratio:21-1. .Fuel: Kerosene. Build by Find Hansen Denmark www.findsminimodelhotbulbengines.dk.
