In addition, I measured the thickness of the thrust washers from Suzuki at .8mm apiece.
As Oldfeller suggested, I left the back washer on (toward engine) and that makes both idler gears line up (all 3 teeth across the torque gear grab metal on the idler gear). I left the front (outermost) washer off and bolted the cover on. No gaskets, no form-a-gasket, no spacers of any kind, nothing but case to case. In this condition, the engine will roll over.
The Suzuki gasket wasn't thick by any means, so I won't gain much clearance there. And unfortunately, much of the form-a-gasket squeezes out due to the magnetic pull of the stator when I slide the case on, so I won't gain much there. Since the engine rolls in the current configuration, does anyone know the drawbacks of leaving just one washer on? I wasn't sure if Oldfeller suggested this as a test only, or as a permanent solution.
It seems like it would work, but what works in my mind doesn't always work in the real world
