I'll do my best to verbally explain this since no one else has stepped up. I'll assume that there's no timing tape on the balancer. Take a measurement on your timing tab from the O-TDC hash mark down to the 12 degree hash mark. Multiply that measurement X 3 to come up with the distance where 36 degrees should be on your balancer. Mark this position with some white paint/chalk on your balancer, while revving the motor up to 3000 RPM, check where your timing mark is on the timing tab. That's the total degrees. I use a very simple Timing Light (without the dial) and make sure the Vacuum Advance is dis-connected. 36 Degrees total is a great starting point and motors are usually very happy righ there.
