Hi CJ

Is that the same engine that's on those WW2 nearly all cast iron generators?
If so I do not think it's that dangerous
That little engine would hardly pull your hat off
I guess it could pull about 10 amps at 12 v
I shudder to think how it would go on a mower
Mine ran well Easy to start with its electric start
I still have it somewhere. It did not go well after it was dunked a few times on.the front of my old LandCruiser
Very heavy but on those days no body knew what GVM was.
All the best
Jeff
