<x-charset iso-8859-1>No sooner I said this I found something helpful, to make sure I'm not
overlooking anything.

It doesn't have diagrams, but its something to build on.

ooting/Engine%20Fails%20to%20Start.htm

I'm going to keep a collection of notes from this project, especially from
Jim and Steven.  Maybe between the four of us something can be put together.

I looked through the archives and found ingition troubleshooting to be
something fairly common.
