There might be a little confusion on my part. I assumed the timing marks on the different harmonic balancers are different. Thinking about it, they should be the same.

Either way, the old 230 balancer's timing mark was off because the rubber dried up and moved. I hope the new balancer will confirm this when I hope to see the mark when I try to adjust the timing.
