I agree DR,If the machine has a mag,the rest of the electrical system has no effect on ignition. My comments were directed at battery ignition systems. The main disadvantage I see to a pos ground system is that it is an odd ball in a world of neg ground systems. This can really get you into trouble if you try to jump start a neg ground machine to one with pos ground by connecting one jumper cable to the "hot" battery/starter connection on each machine,and the other jumper cable to the frame/engine block of each machine. This will cause a dead short equal to the combined voltage of both batteries. The same goes if you let any metal parts of both machines touch while jumper cables are correctly connected.
