Jim,
Your constant attacks on Dick Taylor are getting tiresome. You're out of
line.
Dick didn't say the radius of the arc changed, he said the length of the
arc increased as the valves opened. Check your high school geometry
book. It will explain to you the difference between the length of an arc
and its radius.
