Pull the coil wire from the mag's cap and hold it
within 1/8-1/4" of good ground and have someone crank over the engine to see if there's any fire.
You may want to use a pair of insulated pliers so you don't get bitten. If there's no fire or very weak fire clean those points with some 320 wet or dry until nice and shiny. Make sure the gap is at .013". If the points are pitted replace them. You should have a nice hot blue fire. Your coil could be weak too if its the original. One other thing is some of the mag's lose their magnetism and this is what creates your fire when they pass by the coil. This is easy to check by removing the coil.

Take a flatblade screwdriver and touch those magnets. They should attract that screwdriver with some effort. It's not going to shock you either. Don't pull that mag off the engine until
you see where the rotor is pointing. Make a sketch on paper and don't rotate the engine while the mag is removed. Hal
PS: Here's a mag with the magnets exposed.
