After a pretty thorough search, I haven't had seen mention of the factory settings on the .22 Mrod. And I have adjusted mine a bit and don't know how to get back to them.
Here is a pretty good discussion of them, but for the .177 http://www.crosman.com/blogs/croswords/?p=173
This author defines a good terminology for describing settings. In fact the whole article is really good, but it is for the .177
* What I am labeling “Hammer Tension” the manual calls “Hammer Spring Pre-load adjuster” and for shorthand, I label “H”. When I say ”6 H”, I mean that the hammer adjustment is six revolutions in (clockwise) from the minimum starting point of completely (counterclockwise) out.
* “Stroke Adjustment” is what the manual calls “adjusting the striker” or “hammer stroke” and I am using “S” as my shorthand. So “2.5 S” is shorthand for when you have the stroke adjusted two and a half revolutions in (clockwise) from the maximum starting point of completely (counterclockwise) out.
* The “Transfer Port Adjustment” is what the manual calls the “metering screw” and I am using “V” as short hand (for velocity or “venturi “). The starting point is all the way (clockwise) in.
So, any ideas on what the H, S and V settings are from the factory for the .22?
