base timing keeps advancing by itself...

Your dampener wont know where tdc is if the ring has spun.

What ignition box, 4 or 5 pin?

Pull the distributor, mark the gear inline with the slot...run it... pull distributor again and see if the line is still inline with the slot.

If you dont check that stuff, like verifying tdc on the dampener... we're done. Get a book and disregard it 'instead' of us.

Thank you, I understand and acknowledge that the dampener may have spun. I was addressing ray's timing light concern. I'm not 'disregarding' anybody. I am also not in the habit of taking orders from impatient strangers on the internet. We are engaging in some troubleshooting discussion on a forum page until I am able to dig deeper into diagnosis. If that angers you, move along.
