         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.

Don't some alternators have internal or external fans that need to turn a specific direction in order to cool properly?
