Hey, started my top end rebuild. So far everthing has been going well taking it apart. I am in the middle of cleaning the cylinder up to take in to be honed or bored. The fiber gasket that goes in between the cylinder and the cases is on there like glue. Any tricks on how to get this thing off? I have the head soaking in solvent, but so far has not done much to loosen it up. Would i be safe to try a razor blade or could that damage the surface? Any help with this is greatly appreciated!!
