Hi Jeff,
It's not likely that you ruined the MC, though it sounds like it's the
MC that is at fault.
Why don't you take it apart again and check that all the little pieces
are there and that they are pointed in the proper direction. It's
possible that a minor mistake was made that causes this frustration.

sleeving and rebuilding.
