Sir, Could you tell me from which direction to remove the McCoy .049 contrapiston? Down from the top of the cylinder, or up from its bottom? Mine is frozen with age, and I want to be sure I don't damage the cylinder while punching out the contrapiston., and I'm surethe 60-year oldengine won't run without being able to adjust the compression.

Any help you could give me on this question would be appreciated.
