Hey guys. I have a "green machine" brand torpedo heater. Thing looks 20 years old, maybe older lol, says 150,000btu. Runs on kerosene or diesel. Last year i ran kerosene in it with no issue. This year im running diesel because its easier to get, and it doesn't want to ignite when it gets really cold. Ive mixed the diesel with stuff that stops it from gelling, but even at 30 degrees (which i dont think is that cold) it has troubles igniting. Ill plug it in, let it run a minute, and unplug it, then repeat that process til it fires. Tonight it is 10 degrees, and its not going to start, period. This isn't normal behavior, is it? Like, if i go spend 300 dollars on a brand new unit, that is capable of kerosene and diesel, i wouldn't have this problem, would i? Was just wondering if anyone could give me some advice on some things to check to get this running? or any other advice is always welcome.. I took it apart and took out the spark plug looking thing, (ignitor, i thinK?) and cleaned it up, and that made no difference. There is definitely diesel flowing because after 30 seconds of running, and it not firing, it starts spitting liquid diesel out the front of it. It also smokes after about 30 seconds to a minute of it not firing..
