My first built hot-bulb engine was a so called "four poster" engine, with fly-ball governor

controlled injection-pump, and a water-cooled injector.

          

Fly-ball governor controlled injection-pump.                       Water-cooled injector.

The engine needs a continuos flame from the blow-lamp to run.

The fuel is kerosene. and the bore and stroke: 20-22mm.

    Four-stroke  lamp-start  horizontal  hot-bulb  engine. Built 1990.

My next built hot-bulb engine was a horizontal engine, with fly-ball governor controlled

injection-pump, and still a continuos blow-lamp, to heat the hot-bulb.

A close up of the fly-ball governor, site-shaft with injection-pump cam and valve cams, cylinder head with

The fuel is kerosene, and the bore and stroke: 20-22mm.
