I believe the most conventional way of describing rotation is looking at it from the pulley end so CW in that scenario. If the commutator on that generator is at the back end like most other generators, then I would have to agree that looking from the back or commutator end, rotation would be anti or counter-clockwise. Looking at the sprockets, with a direct chain drive the the generator can't help but go the same direction as the motor at slightly faster rpm than engine.

Not that familiar with the third brush systems, but on conventional generators if the field is grounded directly instead of thru the resistors, voltage can go very high. I believe the third brush types rely to a great extent on system load to "regulate" do they not. No load equals high volts which is why you hear tales of blown bulbs when something is disconnected improperly.
