Your electronic ignition is misfiring and you need a commutator that actually holds up in the heat. The HKZ-101 is a hermetically sealed Hall effect sensor that sinks up to 40mA and works from -40 to +150°C. No contact wear, no arcing. Drop it on a bracket, wire the three leads – red V+, black earth, green signal – and you're done. Resistant to petroleum products, so it lives happily near the engine
