Retained air can be increased by reducing the hammer strike, or deceased/eliminated by increasing the hammer strike.... If you are experiencing it now and not previously, did you increase the hammer strike to the point of setting the spring?.... When I am setting up a retained air pumper, I try and get 2 shots of the same velocity, or very close, so you have 1 and a follow up.... Bob
I think I am right on the edge on the hammer weight, by adding some more weight,it may result in a slightly faster shot and use more air from the next shot, therefor reducing the number of retained shots?If you look at the progression of the shots, most of the higher fps readingscome at the end of the string, which I take to mean that the internal pressure of the valveis lower, so the higher fps reading is shown.Which would indicate that the hammer weight needs to be increased more?Or hammer spring needs to be heavier weight?I just added 100grs to the Peek hammer, and will test for the results today.I am kinda taking a SWAG here, as I don't under stand it all.
