I ordered some parts from Crosman today. While I had them on the phone, I asked if there were general or starting settings for the hammer spring and hammer stroke for the marauder pistol - incase the settings had been moved. The rep told me the recommended settings and also sent me an email. Here is a partial screen shot of the email that shows the settings:
I agree that the hammer spring and hammer throw settings should be recorded prior to making any adjustments, incase one would need to go back to them.
Anyway, incase someone needs a new starting point, this is what the manufacture recommends.
Hope this helps.
