There are so many ways to set the two that I don't know if anyone can give a ratio. It is really kind of a test and try method. I usually adjust the hammer spring first to about 4 or 5 turns clockwise with the stroke full counter clockwise. Then play with adjustment of the stroke I generally leave the stroke fairly long like at most 1 or two turns clockwise. But these are no hard rules. Actually, the original factory adjustments where not bad settings.
Stock factory according to Crosman is:Marauder pistol settings factory Hs 4 turns clockwise 0 is all the way out ccw Ht 4 turns clockwise 0 is allThe way out ccwThis way you can always go back to stock if you don’t like the new settings Mine is stock factory tune I haven’t touched it. Likes everything I put in it.
