Thank you for the useful information Louis, I've gotten the flywheel off using wedges to maintain pressure with moly oil sprayed on it, took an overnight, but it popped off without damage.
Dusty, but nice shape under there, I'm going to test the coil, but replace it either way, the one in it looks pretty old.
Going to find a manual that shows how to remove it, odd the coil screws come in from the bottom and un access able without removing the plate.
Unique little motors, they are entertaining.
