I'm sure there is a better way of testing the driver coil than what they used back in 1976 (now obsolete). So I won't comment on that except to say the resistance spec is 2.7 =/- .7 Ohms across the winding and infinity to ground. I would say that you probably could buy a spark checker at an auto parts store, but I've had mine since the 1950's so haven't gone shopping for one.
OK, so you said you cleaned the points, so I won't dispute that. But if you have a decent multimeter, check the resistance across them (with wires disconnected). Resistance should be zero Ohms on your lowest test scale. Not one Ohm, or half an Ohm, but zero. Otherwise, it won't have spark.
