I am not saying Boyers always kick back, just there is no provision to prevent it on the Boyer. Even the stock points will kick back because at their most retarded position they still have a bit of advance, nothing a mighty kick will not overcome on either the Boyer or stock points, but sometimes, just sometimes, that mighty kick may not be mighty enough and your starter leg could bear the brunt of that fine motor refusing to wake up on a cold morning.
