test for sparks without a sparkplug …just insert a screw backwards in the boot and hold hit near the frame .5 inch it should jump or use a air gap spark tester
try running the engine in the dark…. look for jumping/arcing high voltage along wires etc…
test the magnets to see if they hold or pull hard on a screwdriver
what is the ohms readings on the HV secondaries between boot and frame ground (wiggle boot clip while testing you should read 4-7Kohms depending on coil type)
try adding a test ground wire between the mag plate and the engine body creating a good return path for the HV
if you have spare condensers swap out the one on the top set of points ….. if not interchange the condensers since the bottom one is known to work ok
keep (tuck) coil wires away from rotating shaft
clean points with an acetone/carb cleaner wetted business card
