X-Mag Help, possibly LvL 10?

[Eckzlnt]

Ok, I've read hundreds of posts, and tried everything I can think of, but I still can't get my xmag working comfortably.

I recieved my x-mag, and the LX was set up using the .5 carrier 1 shim and the shortest spring. That lasted about 1000 or so dry shots and about 100 live rounds. Then it started to get some bolt stick, where the bolt was staying out for like a half second every few shots. I added another shim, and the problem went away. A few hundred more dry shots it was fine. Playing this weekend, after a few hundred shots, the problem was back, but worse. (Good thing I had my old RT Pro to keep playing)
It was firing multiple shots per trigger pull in all modes.
I fiddled with it, and now the bolt just seems to get stuck open leaking air.
I tried adding more shims, until it leaked, no luck
I tried going down a carrier, it seemed to stick worse.
I tried going up carrier sizes, it still seems to stick.
I am able to use the 1.5 carrier, as it starts leaking some with no shims, but it still sticks. when it sticks, it also has to be manually pushed back to stop leaking air.
I have also tried using all 3 springs, none seem to work better than the others.
This is with both the breech removed, and also with it securly in place with the barrel.
The closest I've gotten it to working would be in E mode, but if I try and fire rapidly, it does it still, and all the time in M mode.

Also, it seems like I have to "jump start" my gun in E mode. I have to fire it at least once in M or hybrid for it to fire when i pull the trigger in full elec, or else it doesn't fire. I would have to do that every time i stop firing for like a minute or so, any ideas about that?

Sorry this post got so long, any input and advice/help is greatly appreciated.
Thanks

I had alot of trouble w/ my LX when I first got one on my EMag and what I've been having luck with is using the carrier w/ 1 dot and 1 line w/ the spring w/ the clipped end and 2 shims this setup has worked flawlessly for me for over 6 mos. Another good thing about my setup is that it leaks when it needs oil so its like an indicator. Try using this setup. Some people have had luck using this setup and others haven't. Give it a try.

Thanks, I got it to work last night, with the #1 carrier, and playing with the input pressure a little bit. But now I think I have the "runaway"/full auto problem.
In M mode I can hold down the trigger, and it fires non stop, and each pull in elec mode fires 2-3 shots. It's even gone into runaway a few times trying different things where I had to kill the air to get it to stop.
Would this fix my problem?

Thanks.

No, thats the fix for runnaway in E mode. Your saying your getting issues in M mode.

Now lets go back. If I am reading right your initial problem was level 10 carrier but you first changed shims. But eventually you realized this was not it and ended up changing carriers. So lets return it to where you were.

Two shims and the carrier that is now working. I can assume you reused the same oring. You should have. That was the "Broken in" one.

Now if your now not locking up on the sear... Runnaway in M mode. You have something else to deal with. Possibly something that changed when you did all this other stuff.

You should be trying to set up your middle red spring though


Now you need to look at the On Off pin and make sure it did not get snapped off slightly at some point in removing the valve. You need to measure it.

Also examine the edge of the sear. Make sure its not oddly and tragicly chipped by something.

After that You need to set your output to 800-900 and go from there.

Another thing to do as prevention is to directly oil your regulator pin assembly. It could be sticking and it won't hurt to eliminate this. That in the back part of the valve. It will be dry and if its sticking some it can cause odd charging problems. Do that as well. Take it out and oil it and reinstall it.

If you were experiencing runnaway in E mode then this all changes. And yes the Polarity issue comes into play.

So reexamine the things I am telling you to look into and get that set up back to where it was before but just using a smaller carrier and then go from there. If you need to then turn the velocity up a bit. Sometimes it can slip and not cycle all the way if its on the edge of filling properly.

ok, Thanks, I'll see what I can do when I get home from work.
As for the On/off pin, It does not look damaged at all, and I swapped it with my RTP on/off (which is longer) and it still did it the same.
Thanks for all the input so far.

[cphilip]

Well perhaps but shorter pin would be most likely to cause it and the emag is shorter than the RTP but... still.... thats more than likely not the problem. But just something to check

The E-Mag on off pin should be 0.712" w/ brass top and double o-ring top or 0.725" w/ aluminum top and single o-ring top.

But the RT-Pro is 0 .765"

So putting a RT Pro pin in an emag isn't gonna do much for ya. Or is not a good test is what I am getting at. But if it did the same thing rather than not fire at all then I would still suspect the reg assembly or on off orings right now.

[Eckzlnt]

Yeah, I only checked the RTP on/off pin because it's longer, and they say that too short of a pin can cause full auto.

Anyway, I measured the pin, and it's the 0.712" one, but I am unsure what you mean by the brass top w/ double o-ring or alum top with single. What o-rings am I looking for, or where should I be looking? I don't have the o-rings labeled 15 or 16 in this diagram

which i think are 4 and 11 in this diagram

http://www.airgun.com/xmag/html/oring.html

but that seems weird to me that I don't have them ???

[cphilip]

Well what color is your on off top? Brass or Silver looking?

And what oring do you have in there in the hole after you remove the on off? A little black one or not? A big white one or not? A little white one too? Could you have lost some of them? When you were working on this thing?

[Eckzlnt]

It has the brass top, but there is not any o-rings. There weren't any in there the 1st time I took it out, and don't think I lost/dropped any, but you never know. So, I'm guessing there should be 2 white o-rings? or one black one? right now it's just a black hole. And do these o-rings come in any parts kit? or the same as other ones, maybe possibly canibalize my RTP just to see if I can get it to work?
Thanks for all your help so far, I really appreciate it.

[cphilip]

Ok they should be in there. The only other one is the black quad oring. Make sure you don't have one of those. But sounds like your problem! And yes they come in a parts kit and yes if you have the Brass one then the RT Pro ones will work. Look and see if it has them.

[cphilip]

..oh its possible if the bigger white one is not in there that the little one can come out stuck on the top of your on off pin. If there is a little one stuck on the top you only need the bigger one. If not you need both of them

But make sure there is not a black quad hiding down in the bottom of that littler hole in there. You see a smaller hole and a larger lip around it down there?

[Eckzlnt]

There is no black one in there, and I think both are missing. Yes, a small hole, and a tiny lip.
my RTP has just one white o-ring, and I tried that on/off in the xmag in it wouldn't fire. So, are they in the RT parts kit? Why aren't there any paintball stores open now?

[cphilip]

Yes they are in the parts kit. The RT parts kit. Sounds like your problem.

[Eckzlnt]

So, which O-rings exactly are the ones to go on the on/off pin? And they just go on the pin, like one on the other, or what else? Thanks again.

[cphilip]

Since you do not have the old ones to go by your just going to have to fumble in there till you figure out the two. One goes in that space down there and the other one will then fit inside it down in the lower smaller hole and ALSO go around the big fat end of the on off pin. One larger in first... smaller one on back of pin to guide it on in there... and in she goes. Smaller one is normaly whiter than bigger one.

PS i don't have my tool box or markers handy or I would meansure them for you.
