Two thoughts come to mind. 1. Front cover and
timing tab don't match the balancer markings. Not
uncommon with Chevy's and Fords both.
2. Balancer ring has slipped because the rubber
deteriorated. If this is the case, you need to replace
the balancer.
If it's the wrong timing tab, don't worry about
it. Timing light just gets you in the ball park for
referance. Continue to time it by ear and it will run
better.
