[SEL] Fairbanks Morse ZD Flywheel Magneto Timing Mark Question

[MaytagTwin at aol.com]

Hi Francis,
Can't you determine top dead center by pulling the plug and sticking a  dowel 
pin in a little ways, wedging it securely, then turning the flywheel  gently 
until the piston touches?  Mark a place on the flywheel and then  turn the 
other way until the piston touches again.  Mark that place.   Halfway between 
them is top dead center and half way between the going the other  way is bottom 
dead center.  You can run a tape around the flywheel,  determine the 
circumference, and with your pocket calculator you can divide the  circumference into 
360 parts and find the degree distances from TDC that  concern you.  Once you 
get this worked out, you are ready to time the  magneto to fire at your choice 
of marks.  Once you get it running, I  suggest you make new marks using a 
chisel or punch.

Is there  any other 
procedure (other than using the flywheel timing mark) available  to time the 
magneto?
On the bright side, the good thing about finding  these discrepancies, it 
tends to make the gray matter work in an overtime  mode.
