Well, there's timing marks on the damper and a timing tab on the front cover so in theory you should be able to use a light on it to see where it is. Your light will have to be compatible with a multi-spark system.
Just for grins, one day I tried to get a look but couldn't see the marks with the belts, brackets and whatever else was there. It was hotter than hell that day so I didn't do much more than just take a couple of quick stabs at it, then said hell with it.
You won't be able to change ignition timing though, since that would require moving the crank sensor and they're not adjustable without modification. This would be moderately difficult and shouldn't be needed for an SC to run within specification anyway.
If it's acting like it's out-of-time ignition wise, I'd be suspecting a broken damper.
