If you use a standard timing light, try and get a timing tape that goes all the way around your balancer, it glues on....I use clear nail polish to seal it on when it's on. That will give you 360 degree measurements. The other option is to get a dial back timing light. You set the timing on the dial, for ex. 36 deg., and then when you look at the zero mark on your balancer and they line up, you're there.
