Hello from Holland, I bought a 1020 in Sweden last summer, working on it now. Burning now, rather good, but not like it should. Having read this topic it might be a little too small mantle but I am not sure. What happens is a very small leakage on the bottom of the vaporizer giving the effect of fuel damping because of the heat. But I find it very difficult to screw the vaporizer tube on the box in a way there is no leakage. What could be the problem? Regards, Ton.
