The flywheel contains 13 permanent magnets. 12 for the generator and 1 for the ignition. No input is used to run generator or ignition other than turning crankshaft. When hydrogen gas fuel is made at spark plug , the engine starts running. The battery was used for the starter motor only, then completely shut off. Power to make electrolysis is then coming from generator at idle speed. Salt water is allowed to flow into top of carb from hose + bottle. Diodes needed to get DC to make low efficiency electrolysis of water. Fuel gas forms at tips of spark plug and fires same time. The added wire coil changes the timing ,as is needed with hydrogen. The spark plug receives what is called pulse PEAK DC current as about 10A. Spark plug was changed to Champion QC12YC at 125 ohms , rather than original 4000ohms resistance. They also come apart to remove resistor to get a Zero ohms racing plug. ( copper #12 wire segment replacement)
You can verify an old used engine would just run by adding 70% alcohol, or acetylene gas from carbide stones + water added, and also Ether spray into carb. The sound of Nathren's water engine on hydrogen sounds like a water pump. Youtube (2 )videos by S1R9A9M9

Ohm's law was still in effect last time I checked. So if you raise the voltage you decrease the current. The amount of power in the circuit stays the same. Energy is power over time. So if the power is constant and you choose a time interval, the energy will also stay the same.
Why does this matter? Because the electrical energy does not come out of nowhere. The engine has to do some work to turn a magneto (or generator, or alternator). Whatever creates the voltage potential in the first place takes rotational power from the crankshaft. The engine has to convert fuel into expanding gas to turn the crankshaft.
Let's just imagine for a minute that firing a spark plug inside the cylinder of an internal combustion engine filled with air and salt water actually ionised all the water molecules and now it's an explosive mix of hydrogen and oxygen molecules. The water molecules were held together with a force that required an energetic discharge in the spark that was greater in order to break them.
However, the amount of energy available from combustion of hydrogen in the presence of oxygen is about the same. For the purposes of this thought exercise we'll say it's equal. So we've put a certain amount of electrical energy into the system to crack all the water molecules and make them go boom, and now we need to take the energy released from the boom to push the piston, turn the crankshaft, and work against the resistance of the magneto in order to generate the electricity to make the next spark.
if you had an engine that was 100% efficient in turning the potential energy of the hydrogen/oxygen mix into rotation, you might be able to imagine something like this. But the very best internal combustion technology tops out in the low to mid 30 percent region. Then you've got friction losses from bearings, gears, and couplings, internal resistance in the magneto windings, the air resistance across the spark gap, and finally, the pin that bursts the whole bubble:
You'll never get more energy out of the H and O by burning them than you put in to crack the H2O. That would be one serious magneto in order to get the output you need, and I don't think a lawnmower engine would be up to the challenge of turning it over.
Have you got a demo unit available for testing?
