You can start engine 3 without the external power and air? Every time I tried the KB6204 start, nothing happened at all. My guess is that if it's possible to start it without external power and air, as you seem to suggest, then I must be missing something. This would clearly be a case of the problem being me.

I have been using my method since I discovered it. So I got into a bad habit of not doing it the right way. I'm working on changing that.
