if you put it on tdc according to the balancer thats fine and dandy, but you have to remember it comes to tdc twice, once on exhaust and once on compression. Put your finger over the spark plug hole and if you feel alot of pressure on your finger or it blows your finger off the hole, you are on compression and when the balancer says you are at tdc, stab it pointing at #1. If you stab it on tdc exhaust then you are 180 out.
