Thats a low compression mower engine. Modern automobile engines are indeed quite sensitive to predetonation from slower ignition times offered by most alternatives without being designed for them.

If by "design" you mean a different cam profile to drop the dynamic compression ratio then sure.

Maybe this can be handled by adjusting valve timing in software.
He has run a gasoline engine on a whole slew of fuels, including some that may be surprising, such as isopropyl alcohol, various solvents, crude oil, and a 50% diesel gas mix.
Gasoline engines can also run on pure propane, but the fuel pump, tank, and some other parts do need to be replaced.
I guess the point is that gasoline engines are not in general super sensitive, while they still could be more optimized for certain fuels.
