just purchased this car recently..this i my first oldsmobile ever, (and i love it) i'm trying to set the timing on the engine, but having trouble locating the "saw mark" on the balancer. i did eventually find what looks to be a saw mark on it, but it is only on the edge of the balancer, and not marked all the way across.....is this right?? thanks a bunch, Rick

 

Yes that is how they are for that year.

 

THANK YOU very much!!
