360 timing questions

If I go to start my car and it starts at 15 degrees and reaches 800 or above in RPM's and the MSD swithces to 3500 degrees and then stalls. I have to shut the msd off and then turn it back on or it will try to start a 35 degrees This is the only system that will let you run a locked distributor correctly. Otherwise you need a kill switch to flip on after the motor is spinning. If a plug fires a charge at 35 degrees before it reaches the top it will try to spin bacwards, I have seen motors destroy starters when this happens
