LPR ADJUSTER CAP AND GAUGE MESSED UP~help if ya can

[faceplant44]

Hey, I just got my Evolve Kit last night and have run into some problems. First the lpr adjuster gauge is sooo inaccurate it's not even funny. I set my LPR to 100 almost exactly w/ my tool kit and it had no shootdown etc. Then i put on the lpr adjuster, spring and that piston thing in in the order showed my the instructions and by trigganometrys.

I set the screw flush and put the gauge in and it was at 100. That was normal but i could not get it low and still consistent. I couldnt even get it at 60 and to be consistent. At this point the gauge stops at 25 psi when degassed and does not go any lower. When the screw is flush it reads 125-130 instead of 100 which is the actual amount being pushed. i tried adusting it considering it's probably what ever it read minus 25-30 and so i adjusted it to about 90 and it would shoot once go down to 60 then take atleast 3-4 seconds to get back up.

At a few points in adjusting it it would go 100, 95, 90, 85, 100, 95, 90, 85, 100, and so on.

I haven't even gotten to try the volumizer on it yet because the lpr adjuster is giving me such a problem.

I also just found out when takeing the gauge out of one of the holes in the adjuster when i went to put the small flat head screw back in that it was partially stripped already. I could see metal shavings. Now your probably gonna say that you screwed it in way too hard but I DIDN'T thats why it pisses me off.

I actually ordered this once they advertised the new kits and ordered it figureing it'd be the new version. well they sent me the old and talking to them they said they will be sending me the new updating stuff because it was their mistake but i'd like to get this version working while i have it.

Tell me your thoughts. Thanks!

First, I have to tell you were real smart in putting the Newton LPR Cap first to try and get that working before attempting the Newton Valve. That is just some good thinking. Props to ya!

I feel your pain with the Newton LPR Cap. Here is why:

When I first put the LPR Cap on (as you saw in my instructions that I posted with pics), I was able to set the stock LPR to 100psi and then easily install the LPR Cap and bring it down to 50psi without problems. At that point I did not test the set for consistency or shootdown.

When I did get to test it, I could never run it without shootdown. I had not removed the LPR Cap. I just made adjustments using the adjuster screw and I would always get shootdown, even at 65-70psi.

So I was a little upset and decided to take it off. After I cooled off for a couple of days, I put it back on (stock LPR at 100psi) and realized that I could now not get the LPR below 60psi using the LPR Cap adjuster screw. It seemed that I had a short screw for the adjuster screw. So I picked up a longer screw (12mm) and put it on.

Even thought I could not adjust the LPR Cap below 60psi, I got no shootdown at all with the LPR Cap on at high rates of fire. Could it be that at this install, everything was aligned perfectly and that I just didn't have a log enough screw (keep reading and you'll see what I mean)?

That leads me to my new problem. With the stock LPR set to 100psi, I can put the cap on and slowly turn the adjuster screw in and it gets to about 70-80psi and then with just a very, very slight turn in further, it drops to 0psi. Sometimes even at 70psi, I can fire twice and then it drops to zero. When I back the screw out at this point, the LPR charges back up. It seems like the LPR Cap is stopping the LPR from charging with air.

I have a sneaking suspicion that the problem may be the cone portion of my kit along with the spring. You'll see that as you screw in the adjuster screw, the opposite end of the cone, is supposed to sit into the brass portion that is in the LPR Cap. I am almost certain that my piece is somehow not going INTO it but resting on the edge. It doesn't want to align itself into the piece and when you screw it in just a hair too much, it presses into the LPR and shuts it off. That's just my guess. It is like the spring is not allowed to function.

I even tried presetting my stock LPR to over 100psi and under 100psi (say 80psi) and then try the Cap again with no luck.

I think that both of our problems may be related.

What gets me is that some people are using the Newton LPR Cap without problems and some run into all types of problems such as we are. Could it be that this is the case due to every LPR being slightly different? I don't know.

BTW - I did read that someone had easily stripped their screw where the gauge screw into the LPR Cap.

Well luckily i work at a hardware store so i will try that 12mm screw and see how that works out. That does seem like it would make sense because that piston that goes into the spring isn't long enought to hit the other side so w/ the shorter screw it wouldn't be able to compress and fit into that hole in the opposite end of the cone. Soo with that said. I'm gonna try a 12mm and see how that works out.

About the lpr gauge screw it is not totally stripped but if it starts to leak i'm gonna have to get another one and hopefully evolve will be cool about it and just send me a replacement.

Also what is the exact size of the screw. Is it metric. Thank Marc.

[Trigga Nometry]

Also what is the exact size of the screw. Is it metric. Thank Marc.Yes it is metric. It is a M4 size (2mm Hex).

the kit should have been tested more before it was released, from what ive been reading so far its more trouble than its worth.

[faceplant44]

I must say though. Gordon at evolve is being really nice about it. He sent me the old version first off and he's sending me the update for free. Then i told him about the screws being stripped and i might be getting a new one if i cannot get this one to work.

[faceplant44]

Ok well i tried it with a 10mm and a 12mm and still have no luck. I'm still waiting for the update kit so i think i'm just gonna wait till then to fix this problem.
