No correction needed, I am not entirely sure how you know whether the engine 
has the right amount of fuel or not.  This is what I am trying to find out 
(or sources to find out).  I would appreciate any sources of info for where 
I could learn about this.  I am right about just having to change the pulse 
width and/or timing, and IF I can find out whether the engine is 
under/overfuelled, I can adjust accordingly.  At the moment, I am wandering 
around in a dark building, but lights are slowly turning on in various 
rooms.

I don't underestimate anything, I just like to simplify things to motivate 
myself (does that sound like a contradiction? :-)  I like long projects 
which I can sink my teeth into at my leisure, and I tend to have around 5-10 
going at a time so I can switch to another project when I want to freshen my 
mind.
