Engine using compression and make hot therefore dieselfuel selfigniting.

For newbeginner without knowledge... after you has learned how to start dieselengine, then it is so fantastic how easy you can start engine, 2-3 flick at propeller, it will start.

Engine are very reliable and longer life than glowplug engines. More torque and running with bigger propeller and using less fuel than glow engine. Has not some tendency to stop without you are checking if fuel line are not open or lack of compression, not some inconvenient, a bit more vibrating cause higher compression than glow engine. Exhaust smell difference than glow engines. Fuel can damage fuel line of silicon, use fuel line designed for petrol/diesel to example tygon fuel tupe or clear vinyl tube.
