Which mark do I use? I've had this motor together forever, switched over to EFI about 8 years ago and can't remember which mark I used to time it. They are about 7 or 8 degrees apart.
That dampener looks pretty crusty, what does the condition of the rubber look like?
Why would there be 2 marks on it? A correction because outer ring has slipped? May be time for a new one.
ProStockTom sells a nice liquid filled ("cause you can't say "Fluid Damper") unit for a good price. I bought one, and the timing marks are dead on for my application.
