Thanks bud. I'll try to work in it this weekend, and let you know. I also have an embarrassing story as to why my solenoid now functions properly

[ironyusa]

Hey man, it happens to the best of us.

[Thecure1221]

Has anybody tried x rings on the new lurker poppet? Just curious because I saw a lot of people using them on the stock poppet

I have, but I still needed to build up the floor via the teflon tape method. It seems to be working well.

^ what he said.

[midwestscrub]

Just got my poppet and barrel. Installed everything, about to run and grab some paint and will get results shortly, seems to be cycling fine. Happy as of now.

[surflamj]

Definitely had some initial issues. which can be expected with this sort of thing. Got the air through before the poppet sealed, the gun was extremely loud so I only attempted a few trigger pulls. The gun had very little velocity and was rolling two balls out a shot. upon returning to the work bench the spring for the poppet was bent so my tuning is over until I can get a replacement.

The gun is also running a lurker bolt that has been in the gun for roughly a month or so and has been well tuned with roughly 10 cases since i installed it. Settings are as follows.

170 @ the reg
5 dwell
285 +/-5 FPS
1 1/4 turns out

EDIT~~~~

Bent the sprint back into shape somewhat and had another go at it. I don't have a crono so this was strictly off feel and familiarity with the consistency I had pre the poppet install. I moved the setting around per the manual Lurker provided and got rid of the extremely loud ting as well as gained some of the velocity back. At 1.25 turns out id guess I was getting in the 200-240FPS range. I shot a few strings and it seemed like every 4th or 5th ball was coming out at a significantly lower velocity. Without a crono I didn't want to waste paint eyeball tuning. The poppet definitely still effects the sound signature. I'm not sure its any louder, its just a noticeable difference.

I initially started out with the exact setting the manual lists;
140psi
1.25 turns
4ms dwell

immediately it was shooting much better then my first attempt. After shooting a few strings I ended up bumping the psi to 160 and the dwell to 4.5ms. So the settings I am currently sitting at are:
160psi
1.25 turns
4.5ms dwell

I'll be sweet spotting it tomorrow at the field and hopefully get it dialed in.

Can the stock poppet spring be used with the lurker poppet? Or do I need to wait for a replacement?

The stock spring is barely long enough for the hole, my guess no

I hadn't even dropped it in to check. When I saw the spring was bent I immediately face palmed and came here.

[imped4now]

Straighten it out as well as you can and run it. It's not a critical spring by any stretch.

[rwaldt]

would cutting off 1/8 to 1/16in off the back cap on the mini help with the velocity problem?

ill give it a shot. I wanna get this thing dialed in so bad!

[ironyusa]

If you want to cut it, then 3/4" seems about right. I found a random spring in my bag tonight that I'm going to try. Aside from initial air up the spring isn't really critical anyway.

[theblackoutsavage]

Still waiting on my order of the poppet and lube to arrive.. I ordered it during PBE and still haven't got it and Lurker doesn't seem to be answering any messages I sent him. I mean, I know he's busy and I appreciate that but a month and a half later is kind of frustrating.

[ironyusa]

I'll tell him this is here... Go ahead and PM him your info.

Alright, I did. Thank you Irony

[Clark Gryphyn]

I noticed some anomalies with my solenoid when I was testing things the other day, so I took it out and cleaned it. Cleaned and re-lubed everything again while I was at it and put everything back together. So right now I'm at Lurker's suggested settings, but with a layer of teflon tape in the poppet groove and a 013 urethane o-ring straight off the stock poppets on there. (I tried a 013 x-ring first and it still had a lot of grab, most likely because of the way the teflon tape sits in the groove. The 013 o-ring felt perfect in terms of grab, but I'm hoping still gives me a good seal.) Based on feel the gun is shooting the same as my 2nd axe, which is tuned at 285 fps, same bolt, stock poppet. I'll have a chrono at home in a couple more days so I can test it out for sure.

[Lurker27]

That's good, because if the settings are the same, the one with the lurker poppet should be very much more efficient.

[minimag03]

Alright, I've got a few questions.

1) Why was the metric oring chosen for this poppet?

2) Could the tolerances of the orings themselves have something to do with the problem?

I was told by someone, who is very knowledgeable about the subject, that many metric orings aren't made with the same tolerances as standard sizes. I didn't really understand why metric oring tolerances were any worse than standard orings, but this guy was an engineer at AKA for years and knew what he was talking about. I don't think he was making a blanket statement about all metric orings, but was referring to the metric orings that are generally/readily available to us here in the US. It appears Lurker confirmed this a few pages back with this post...

I'm aware that all batches of orings are going to have some variability in size, but this seemed a bit extreme. Unless the poppet themselves have tolerance issues with the groove, it sounds like the orings are a little out-of-whack. (for lack of a better term lol)

I don't think the orings are the sole cause of issues though. The Axe is a cheaper gun being produced over seas, so I'd wager the bolt guides aren't being produced with the tightest tolerances either.

I'm really surprised Irony and Lurker didn't go with a standard size oring for these. Irony, you put a lot of time into testing orings for the Axe. You knew the benefits of urethane and xrings in an Axe better than anyone else. And I'm sure you also knew that it's difficult to find urethane or xrings in metric sizes. Lurker has always been one to 'embrace the numbers' while producing a product, and that's why his products kick so much butt. So why abandon all that research for this poppet?

[imped4now]

I would certainly support a change to standard oring sizes. Hell, optimize the groove size for an -013 or -012. I think that would be a design change worth exploring.
