How to adjust timing if you can't see the timing marks?

and you can have those with timing tape and a timing light also....so what's your point??

Nothing is accurate, that's my point! LOL

At least with timing tape and a light, you know where the timing is... still better to know than to just shoot around in the dark? Sometimes 2 degrees can make a noticeable difference but you'd never be able to adjust that little by ear/feel
