It seems someone has replaced the more modern distributor with an older one, with points and a cam. Make sure the point contacts are clean and smooth, and that the point gap is correct (check tune up guide for a '72). If all that is OK, maybe the coil has an intermittent break that opens up with heat. Also, if the coil is made to run with a ballast resistor and doesn't have one, it will burn the points pretty quickly.
I did the opposite, replacing the breaker point ignition on my '72 Scout II with a more modern electronic ignition, which usually needs much less maintenance than the older stuff.
Don't force it - - get a bigger hammer!!
