Hi, Paul....after disassembling my Ross PRSU, it appears that it is  in fact, a 2.85 to 1 ratio,
because it does reverse the direction of rotation.  My next question is, what direction (clockwise
or counter-clockwise) does the flywheel rotate when viewed directly facing the flywheel?  Thanks
in advance for your reply. Paul Conner, Mobile, AL

Facing the front the engine rotates clockwise. So facing the flywheel
the engine rotates counter clockwise.
