First, get rid of the spark test light. Get an adjustable gap spark checker & open it to 1/4". :

Meanwhile, you have a weak spark. The most common cause of a weak spark is a weak battery. Charge it (see tip # 60) and check it .(tip # 49)

Be careful jumping it; see tip # 43).

Other causes of a weak spark, in no particular order and probably not all inclusive, bad grounds/connections, worn plug wires or carbon core (automotive) plug wires, wrong plug gap, wrong plugs or burned plugs, worn out rotor/cap/points, incorrect point gap, worn insulator on the side of the distributor, incorrect or burned out resistor & a worn out ignition switch putting resistance in the circuit. Rarely, a bad coil..
