I have one of them machines similar to what you are talking about but it is for testing the spark plugs only and cleaning them, it was from an old chevrolet dealer years ago. I haven't used it for quite some time now but it should still work but this has it's own spark maker so it won't test the spark comming out ot the magneto. I wold imagine if a guy took a long spark plug wire and just used the machine for putting the pressure on the plug it would do the test you are talking about.

What you are looking for is something that tests the spark comming out of the coil to see if it is strong enough, there is a really reasonably priced gadget like this on ebay in England Item Item number: 160673739092 also there are many others like it that may be cheaper.

This gadget is designed to test the spark on GM HEI ignition systems wich usually put out about 80,000 volts that should be very similar to what a good magneto should put out maybe you want to give one of these a try.

Just a thought,
