Consider you want to verify spark timing against piston position.
With a point triggered ignition, you set the points to break at <xx>mm BTDC (that figure from your friendly service manual).
What about a mag setup? I have yet to see a BTDC measurement for the piston for spark trigger...and how do you determine the exact postion of the FW for firing anyway?
Point is (in this case) you either don't trust or want to check the stator marks.
Thanks!
