I have been trying to use a 740 coil pack but the king lead dose not fit. the coil has a very small connection and my lead is too big. Im trying to find out if its the lead or the coil and if something can be done about it. The king lead is the same connection on both ends fits the dizzy but not the coil, but i found a lead that will fit the coil (smaller connection) and not the dizzy but i dont know what this is from.
