Should be easy to verify using an ohm meter and an accurate dial indicator. Set the timing accurately as described in the manual. Zero the indicator on the piston at TDC, making sure all the backlash is out and at the exact point of reaching it. Rotate the engine until the points break at the piston you are indicating. Convert the difference in movement in thousandths of an inch until the points break to degrees of rotation.
What has to be considered is there has to be approximately 4-8 degrees of crankshaft rotation to allow the piston rod combination to break over and begin downward travel. Engineers have to allow for that lead into every engine or any timed machine converting linear motion to rotary motion.
