Hi Matthew

What Tom says !  But good that you are looking closer at the action and 
curious to figure out how it works from a hands on approach as well. You 
can get totally lost in this stuff if you first let yourself.  Just take 
the few things Tom lists below for this single one issue.  Try adjusting 
the rep lever height in one section without first regulating the rep 
spring strength, and then in another section do the rep spring strength 
first... then recheck both sections and see what you have then.  Or try 
other such things when you have the time.  Grin... make sure you finish 
by the book tho ! That said, being a little nosy (read curious) goes a 
long way in this business.

Cheers

    Rep lever height and spring strength(or lack of) , jack to knuckle
    orientation, knuckle condition, jack and rep lever surfaces , tight
    action centers ,and maybe a few more reasons.

        READ----- REGULATION !   

    Check your Randy Potter literature.I bet he has a whole chapter or
    more on grand action prep and adjustment.
