WHAT THE F*$)..thanks all

is the pulley completely tight?...do your bolts have any shoulder at all..sounds like maybe the bolts are just a little long and not getting totally tight and when the engine runs, there is just enough give to let it flop some.

did a few things.....i Broke out the old SLEDGE and gave the pulley a few wacks to see if it would straighten out......pulled the belt tighter and titened the bolts up more and i did something right.....IT s working now....Thanks......oh yah......there is still a little wobble i think bolts are a bit long ill go by some shorter one tommorrow
