Need help with rotor phasing

30* to start is to high that's why it's kicking back, not sure why it's less at an idle unless it's retarding it electronically. When I set up a motor to do a break in run I set the crank at 10* btdc
line up the rotor and pickup and lock it down, when it starts it never more than a couple degrees off or right on in many cases. I always use a mopar electronic dist because they never fail me.
Every body knows a failure during a break in run is the worst.
