Bruce,
You sent me a Replacement Part manual for the 12" and 14" Atco about a week or so ago, but it doesn't show the flywheel complete, just all the separate components.
The motor is the slant back type, if that makes any sense, and as the motor is in pieces at the moment, it's a little difficult to send a pic. If you want a pic of how it is on the bench, I can send one tomorrow.
Thanks
