On the overwhelming majority of engines, regardless of whether it is a mag or Kettering, whether manual or centrifugal advance, the spark will be retarded well past top dead center in order to assure relatively safe hand cranking, as described below. A tractor or other vehicle which is hand cranked with the timing closer to top dead center does become easier to start. It also becomes more deadly. If the timing ever fires before TDC while hand cranking, you will almost always get a kickback. The chart in the IH-8 manual clearly shows the H4 magneto "with serial numbers 1353301 and up" is supposed to have a lag angle of 35 degrees. Others have a lag angle of 7 deg. I don"t know squat about IH mags; but I do notice a similarity between what the manual calls "lag angle" and Red Dave"s description of what the impulse does. In other words, when you set the timing STATICALLY, the impulse DOES trip at TDC. But at hand cranking speed it automatically retards the timing to 35 degrees after top center, pushing up to where it needs to be (before top center) at engine speeds. Right, Dave?
