Ancient hot-bulb engines simply refuse to die

It's not impossible to find 100-years old hot-bulb "semi Diesel" engines still in perfect operating conditions fitted to fishing boats. Even though the widespread availability of horizontal-single true Diesel engines from Japan and those copies made in China could sound promising for a phaseout of the "semi Diesel" with its need for some external source of heat for start (usually a kerosene-burning lamp, but sometimes just a few pieces of red hot charcoal can also do the trick), it's not really uncommon to find older British hot-bulb engines not only pumping water in the rice fields but also powering small fishing boats in Pakistan. Maybe that's still the clearest part of the British colonial heritage, along the RHD rule.
