so peole have been having all kinds of problems with their newton kits on all types of guns; even to the end of selling their kit rather than screwing with it

i belive there is a problem in the instructions that where given to the coustomers who purcahced the kit. what i belive is the problem is that one is told to put to many shims into their lpr, upping the stock lpr pressure to 100psi. when one screws in the lpr adjuster screw to bring down the pressure, i belive, it puts to much pressure on the ring springs inside the stock lpr.

im not one-hundred precent sure, and would sombody please correct me if i am wrong, i belive that this would put to much stress on the stock lpr therefore causing shootdown and creeping lpr pressure.

am i close or am i totaly off base

I have often wondered why the kit alls for adding shims to reach 100psi when the stock setting of the lpr's is lower than that. I do agree with your thoughts that the kit might be causing undue stress on the stock lpr and springs. Your thought in on creeping lpr pressure could be correct if the kit was unstable. By unstable I mean not well aligned inside the lpr chamber causing unequal pressure on the lpr and the seal which would cause the pressure creeping up.

The thought of FSDO is possibly but unlikely related to the lpr. However it is happening the air is leaking or spiking in the valve chamber. How and why this is happening it beyond me. I've come up with nothing conclusive as to why some people are experiencing FSDO and others are not. The only thing I have that seems to make sense is the spring adjustment on the valve side. I am sure it has something to do with it but what or how specifically it is doing this. I do believe in my case the screw was in too far on my kit which might have been causing the FSDO as well as needing to increase the pressure to attain sufficient velocity. I am guessing that it was not allowing the valve to open far enough to get sufficient air to propel the ball. Perhaps something here is why I was getting FSDO.

i was thinking this as well, thus i sniped a few rings off of one of the screws that they gave us

i threw it in there and tested down the hammer side of the gun with a longer allen wrench and it didnt feel all that much diffrent from normal

but i have yet to try it out so who knows if it well help

The reason for the 100psi was were experiancing serious shootdown so we gave a % increase over the output.

Currently I have mine setup using the standard LPR and the evolve valve system. Maybe it's going to work, maybe not, but I was never really enthused about the evolve lpr however I did like the idea and theory of the valve and hammer. Those really were the perks that got me to buy the kit.

i have just taken out about 7 shims out of my stock lpr...hopefully when i test it the reduction on pressure on the springs will help

i tell you all how everything works out

I am planning on either playing this weekend or spending some time testing out my evolve valve. I have a theory that while they specifically said use some super glue for the valve seal o-ring this was making the seal very brittle as a result. I will try it without the superglue and see how it does with fsdo and what the seal looks like after a few hundred rounds.

Mine has all the shims, it's at 100psi internally before the evolve adjuster.

It also works great... no FSDO, no problems at all.
