Should have titled the post "magneto rotor timing on a TD14A".
Here's a link to the official IH Blue Ribbon Mag Manual. Be SURE to use the marks for the correct rotation. I'm NOT an IH gas-start diesel guy, but, IIRC, those mags run the opposite direction of the straight gassers. Figure that out for sure and use the correct marks!
ANYHOW, here's the link:http://www.cleancomputes.com/Cub/Blue%20Ribbon%20Service%20Manuals/GSS-5035%20Service%20Manual%20Magnetos/index.html
