It is pictured idling here with a small but sustainable flame. I had to turn it down because within 15 minutes the threaded brass plug and the exhaust nipple began to glow red hot on full throttle. This leads me to believe the entire contraption is bound to self destruct as it reaches the melting point of both brass and cast iron. For this reason my next combustion chamber will be all refractory material incorporating the same pre-heated stainless steel shot glass to vaporize the oil. For now I will use this contraption until my self-destruction prediction comes true.
