Default OS FL 70 Piston Removal

I recently obtained an old FL 70 four stroke in a purchase of several planes. I would like to replace the bearings but am having trouble removing the piston and rod so I can take out the crank. I have removed the cylinder sleeve but can't determine how to remove the piston/rod from the bore. How do I do this?

I know how I do it but if you go into the glow engine forum and OS support Bax can probably give you a much better answer.

should be two holes in the cylinder. Line up the wrist pin with the holes and knock the wrist pin through the holes.
