-Which is why I swear by petrol engines.
Regarding runaway diesel engines: I repaired a diesel engine in a boat once. Thought I would make the old gunked up engine look nice so I cleaned the outside with kerosene. Nice and shiny. Turned out it also cleaned the fuel regulator screw which, without me being aware of it was missing a spring.
I cranked the engine by hand and closed the depressurization valve and to my horror the engine really went off. Turned out the regulator screw with it's missing spring started to move on it's own spraying more and more diesel into the sylinders as it vibrated. It took seconds before the monster sounded like a chainsaw on full speed. The engine got all blurry to look at from the vibrations and I attempted to open the depressurization valve with a big stick which resulted in a white flame bursting up in the air.
Then the engine tore the motor mounts clean off, jumped high up in the air and plunged into the water.
If this had happened to someone else I would have laughed my ass off.
Unfortunately it happened to ME so I got scared to death.
Since then petrol is the way to go.
