Yup, Ken's a helluva guy !
The original gears were drilled such that reversing them back-to-front would
adjust the timing by 1/4 tooth; and using the other pair of holes would
change it by 1/2 tooth, thus allowing timing to 1/4 tooth. The mis-cut ones
come out the same no matter which side is front, meaning you can only set
timing to 1/2 tooth. Since a tooth is about 16 degrees, this is an
appreciable error.
But that's for the TRactor motor, I still don't know if it applies to 6-pot
TRs.
