With this in mind, I think that a question we should ask a 'newbie' is "what elevation do you live?" when they post that 'won't start' thread.
There's information about air density and altitude available at this site: Engineering Toolbox
. More specifically, this page covers air density and altitude
I haven't explored the altitude factor much, I found it when I was looking at air temperature and it's effects on volume (thread regarding that is here
Hope the links help a bit.
