Gee Whitehat... I stuffed cotton in my eyes and was able to make it out. You are correct... ...there is a good question in there.
ANDYMAN,
Ah... on the brink of learning new technique... what adventure!!!! You are going to feel good once you conquer this one!!
What makes you think they set in the incorrect place? Does one pin seem to have multiple set positions? Or are your fighting spring tension and not really sure if the pin is set at all? Perhaps the plug 'gives' a bit and the pin dangles loosely?!?
Tell us what you are feeling. (I sound like a shrink

)
There are some previous threads about spools, mushroom and serrated pins. Since you've used these terms, I presume you know the difference and the plug 'feel' associated with each. If not... research those threads.
While I can't imagine an inexpensive lock with these special pins... I am not familar with the lock you have and therefore won't discount the possibility.
