It’s possible that the rods are slightly bent and binding up when you reinstall the jugs.  Try this:  As you reinstall the jugs, before you bolt them up, see that the jug flange is parallel to the mounting face on the crankcase.  There may be a little play, depending on wrist pin fit and rod fit on the crank, so check it at the limits:  As you face the front of the motor, twist each jug lightly clockwise, then counterclockwise and make sure the differences balance out between the jug and the crankcase.  I apologize if this isn’t clear, post questions if it’s not.

If you find that the binding is caused by bent rods, they can simply be bent back until the cylinder flange is parallel to the mounting face of the crankcase.  The bronze rods are easily bent, particularly when trying to unstick a seized motor.  Rods can also be twisted, actually very common in an un-stuck motor, but it’s gotta be really bad to cause a problem on a Ruddertwin.

Good luck!
