The ends of the springs aren't ground flat like on the original spring so that makes it sit a little bit differently when installed effectively making it a bit longer. 1st couple of minutes using it the water stream wasnt all that strong but after a bit it started working fine. Several hours of use so far and no issues. In taking apart the gun to replace the spring I noticed that the oil port really only seems to lubricate the ram rod, not the spring. So will be opening gun up to let spring chamber dry between uses.
