Setting timing without pointer

Easy. Just get a narrow, flex tape. Measure carefully and accurately around your balancer. I used to find this was easier on some cars by jacking them up and doing it looking up from underneath.

Take the figure you get and divide that by 360.

Then take that answer and multiply x 40. That will give you the measurement in inches for 40 degrees.

Then simply measure that off from your TDC mark.
