I can appreciate not wanting to stray. I do know the fitech documentation leaves a lot to be desired though.. I've had better luck experimenting than listening to them but I'm sure if there's an error in the manual they can tell you about it tomorrow.
As far as not getting spark, great question. It should throw a spark regardless, even if it's at the wrong time.. Unless it can't get to the terminal from being "double advanced"?
Hard sayin', not knowin'.
