What is the effect of the new spring in the valve control knob adjustment on the C3 bumper? Long lasting C3 bumper or less?

It seems like they said it was to help with the return seating of the new valve rod assembly because the new assembly doesn't have the long return spring along it's length.
It probably won't effect the C3 bumper either way because that gets smacked by the hammer weight just the same. On accident I discovered that not having any C3 bumper was producing a very consistent shot string; but it is metal striking metal and not good on the rod's threads if they get loose.

Hi Powerbroker,
the valve return spring has more accurate control in opening and closing rate of the valve. Now owners can’t lower speed to low too prevent jamming pellets. Also the spring can be easily replaced with different strength spring to tune at a set speed and caliber.
the hammer has a pressure fit Delrin as a bumper so no more oring to wear out. The delrin has a smaller bore to minimize vibration and maintaining alignment of the rod. Hope this answers your questions

Vad,
the first modifications for the PP! Nice one.

You mean to cut and if it will increase? Theoretically, it will open the valve longer and increase the speed.
