340 engine timing issue

What you need to do even before you try to start the car is check to make sure the outer ring on the balancer is'nt spun.Take out #1 spark plug.ONLY by hand turn the engine to TDC by the piston forget the timing marks on the balancer for now.It doesn't matter whether or not comp or exh stroke the piston sees TDC twice( use a really soft metal or wood dowel.)once you get the piston to TDC as close as you can. then look at the balancer timing mark.If it's close,cool if not the balancer is bad .Replace it
