from what you have writen i take it what your saying is that there is power at the coil when the ignition is in the run position but when you crank the engine there is no power hence the engine wont start? on the hz usually there are 2 wires from the ignition to the positive on the coil 1 is a resitance wire(8 volt) which it runs on the other is straight 12 volt the 12 wire only comes alive when the key is in the start position to give the coil a 12 volt burst while starting. to prove or disprove this run a temp wire from battery + to coil + then start it. once running remove wire. if engine still running i would guess the ignition switch is knackered or that wire is off or broken.if that proves to be the case and you dont want to [Naughty Pottyword] around with the key, wire in a relay to put +12volt on the coil, switch the relay with the starter motor.
cheers stevo
let us know how you went?
the points are set right hay?

Disconnect the wire off the negative side......
With the ignition on, test for voltage at the positive side on the coil with a multi meter
if you have power.....fit a spark plug in the coil-wire (dizzy cap end) and earth the plug....remove the wire from the neg side of the coil
run a spare wire off the negative side of the coil and earth the other end briefly (scratch it past an earth)you should have had a spark at the plug....if you do replace the points and condenser
if not .....run a wire from the pos battery terminal to the pos side of the coil (remove factory ign wire first) and try the quick earth again, if there is spark you have problems with the ignition switch/wiring.....
There should only be one wire to the pos side of the coil not two as suggested by previous post..........the resistor wire builds up resistance when hot...so when cool (starting) it has no resistance allowing more volts for starting.........
