John,

So because its been rebuilt its harder to do?  I did it with my fingers before.  I know when I took it off it was just about ready to fire.  I assume I just need to get it back to that position let it fire and then turn it backwards and then put it on.

Correct?

I'm wondering if the position has changed since its been rebuilt?

LeRoy
