Have a look at the coil and its supply lead, standard it has a 9v coil and a resistor wire in the harness, this gives trouble ar resistor wire is odd and will not solder or weld and its expansion when hot loosens crimps! If you put 12 volts into a 9v coil it overwhelms (magneticly) the windings and gives a poor spark, also burns the points.
