Stuck Piston

The piston is still stuck after repeated attempts to free it. The present plan is to disassemble the motor and split the cases, then unbolt the connecting rod and free the cylinder. Then I can attempt to fee the piston without damaging anything but the piston and cylinder. A foreseeable problem is that the studs that secure the cylinder to the cases do not clear the cylinder even when the cylinder is raised as much as the con rod length allows. That's a tomorrow problem.
