A direct , but painful, answer to an earlier question. I had "heard" that before I used a very small whiff of ether near the air intake on my VW diesel mentioned earlier. Perhaps the paper air filter blocked most of it? it did start, however in 15 degree below on a battery that was quickly dying. It appears I was very lucky not to have damage as you did. Knowing what I know now, I wouldn't do it again.
