Can't help with flywheel, but it looks like the 3 amp system may contain a diode to rectify the ac to dc, but is unregulated. the 10 amp system uses a rectifier/regulator.
I am more familiar with the Briggs coils and the size and number of the magnets the more amperage they put out. The one wire coil you have may have the other wire grounded to the engine. the coils produce ac voltage and use a diode or a voltage regulator to change the voltage to dc voltage to charge the battery. the one diode is unregulated and the coil that use the voltage regulator is regulated dc voltage which doesnt overcharge the battery and bubble out the electrolyte solution.
Thanks.
I was under the impression that coils with a single wire have a diode included? Thus they put out unregulated, but DC, voltage.
And that coils with two wire put out AC Voltage. This was about Honda coils and may not be correct.
I ordered the stator with dual coils 17 085 09-S. I only found one picture of it not in the diagrams. It appears to have a single wire.
How would I wire a coil with a single wire output to a three prong rectifier / regulator?
Coil Output to one of the AC inputs.
Wire the other AC input to the engine block (ground)?
Connect the positive DC output to the positive terminal on the battery?
It does not matter where the diode is, just so long as it is in there and wired in the right direction.
Now if you think you are going to run the engine at 6000 rpm you are in for a shock.
they are not balanced well enough to do those speeds
they are not flowed to handle that volume of gas
the crank is not supported well enough to run those speeds
the crank is most likely not stiff enough to pull those speeds , particularly as it is a Preditor.
Now a Preditor self destructing is no great loss as they are throw away engines but just be wary of what is near the engine as flywheels have been known to shatter on over reved engines.
Also the power of the engine will drop off as revs increase and may very well be less than 1/2 the rated Hp fr the engine.
And if you think I am talking rubbish pop over to the racing mower forums and read some of the disasters that have happened to people who over reved the engines without substantial strengthening.
If you need more revs at whatever you are powering, gear up the engine's PTO.

I build up Predators. I have used a stock Predator Flywheel for an engine that spins 7000+ RPM. On a minibike. Right under my manhood.
Predator Flywheels do not come apart. Show me one and I'll believe it. Otherwise it is just Propaganda spread by OMB.com.
Installed correctly and lapped to the crank, PREDATOR Flywheels do fine at 7k RPM. Stock Connecting Rods are way more likely to let go than the flywheel.
I have been on forums for years, with people who race karts, and nobody has ever witnessed a Predator 212 flywheel explode. Not one person. Everybody says that they do, but find me someone that witnessed it. I'll hold my breath. Big block engines (390cc or 420cc) or verticle shaft engines might be different. Predator 212 Flywheels do not explode at 6 or 7k RPM.
Now I have never tried with a flywheel with charging magnets, so this will be new.
Stock Crankshafts do fine.
Blocks start to break around 30HP on these 6.5 HP engines.
My heads are usually ported and flow enough to spin 10,000 RPM if I had a camshaft to make power there.
My current engine spins 8500 RPM - using a billet flywheel and makes peak HP around 7k RPM and peak TQ over 4000 RPM.
