Hi Merugo,

You're absolutely right. If you have seen my postings on YouTube under the pseudonym "hopeso", you'll see that I have the tendency to try almost anything just to see what might be discovered. Many times I WILL jump to conclusions based on somewhat limited knowledge and variously, I do add qualifiers and caveats after the fact.

Picture this. A batch of Biodiesel that does not pass the water or the methanol test (after careful washing). So now, put it in a pot and bring it to a boil for a minute or so. The result? An orange, thick, gooey mess. So we reprocess with some sodium methoxide in the usual way and end up with an orange, highly liquefied material. The tricky thing is that no glycerin settles out in the usual way, even after several days. HOWEVER, washing this material brings us back to a yellow, near clear, low viscosity fluid.

I assumed that I had boiled off the glycerine and that that was why none dropped out in the second processing. This batch is still settling out some water but it looks good so far. Should be able to test it tonight.

Ken,

Maybe with a little work, we CAN run dieselized leaf blower engines on oil. How about using a water jacket that derives its cooling effect by running your oilfuel through it. This cools the engine AND thins out the oil. When I make Biodiesel, the base oil is heated to 60C. It's amazing how much viscosity it loses at this temperature.

In addition, you can eliminate that plastic piece between the case and the carb. I believe that this is there to keep the carb cool so that you don't get vapour lock when running gasoline. That wouldn't be a problem with an oilfuel and the heat might help the carb atomize the fuel more completely. As well, porting design might be something to consider.
To avoid the need for a special prime, why not spark ignition? Sacrilege maybe if you're talking diesel, but now we're really talking about getting oil to burn in small engines no matter what it takes. Looks like I'm going to be busier than ever next summer, running engines. Neat.
