Ok here it is from the ROAR 2007 rule book:
8.5.4.2 Timing advance must be fixed at a maximum of 24 degrees measured mechanically. The space between the magnets must be centered on one set of mounting holes, and marked on one side of the can to indicate zero degrees. The brush hoods will be aligned at 90 degrees from this mark, plus the allowed timing. The commutator slots must be aligned with the center of the armature pole faces. A tolerance of two degrees is allowed on the commutator positioning, but not on the overall timing.
So is this not a teched item... If so, then it should not be a big deal to share from the motor masters how to check this... I for one sure would like to know if my motors are not legal....
PS> I see that Garrett is on here looking, come on share with us how to check this... Don't be shy....
