Your magnets should be OK  but it’s the older iron magnets used in prewar motors which can get weak and need recharging. Magnets made since the late forties are made of alloys and will hold their charge indefinitely

No spark or weak spark can be caused by a bad condenser and also by poor connections at either end of the spark plug wires if the points and coils are good. Are the plugs new?  NGK B6S set at 0.030″ are a good choice for this motor.  If the connection to the coils are good, check the condition of the spring terminal inside the plug boot. They like to corrode or come loose over time.
