Don't Honda engines spin "backwards"? Will this be a problem when

using a Honda alternator on a rotary?

Not that a pulley cares which way it turns, but Alternators are AC devices internally and don't care which way they turn either. A rectifier converts AC to DC for the external world.

I understand that there are no electrical issues. I was concerned that the fan does not work well when spun backwards.
