advanced timing school please

I don't use timing tape. Check your balancer for accuracy yourself, either make steal or buy a "piston stop."

After you have either checked the original marks or made a new TDC mark, you can easily mark the balancer by measuring carefully around the outside, and figuring "degrees per inch" to mark off say, 40 degrees. From that 40 mark you can divide in half to get 20, 10's etc

If you DO use tape you want to make sure the OD of the balancer is accurate. Again, just measure around it carefully, and divide by pi
