VW Cold Start On WVO

Old Stinky gave me a little scare today. After some serious loss in power, I changed her fuel filters, only to find the problem got worse. I was pretty much running 100% WVO (Waste Vegetable Oil) at the time, and thought I was in some trouble. After driving some 100km to burn up about 8 liters of oil, I went to the gas station to top up the tank with $10 of diesel. The diesel didn't help. The car wouldn't idle, it would die at every traffic light, sputter, and lack power. After a day of thinking about it, I got into it, and found an air leak at the new filter, sucking air in. I double hose clamped the fuel line, and its running top notch again.

Running 100% WVO has its disadvantages. One disadvantage being it is harder to start. In the summer it starts like it is -20c outside. Here is a video of a "cold start" at about 15c. This was when I had the air leak, I think it is much easier to start most of the time, I will make another video soon.
