** Official Level 10 Problems Thread **

Sounds like your velocity is set too low. If you're pulling the trigger and it's pushing back, but not firing then that means there's not enough pressure in the valve chamber to push the bolt forward and fire. Crank in the velocity adjuster while pulling the trigger and see if it starts firing. Your leak also might be a result of the reg. pressure being too low. Often if it's too low it won't have enough pressure to seat the o-rings and you'll have a leak until you turn up the pressure/velocity.

Give that a try and let me know.

how much can I screw in the regulator? I know loosening it too much will cause it to leak but is there such thing as screwing it in too much? I'll try this tonight! thanks

I'm trying to help him troubleshoot and the trigger is always resetting itself. I tried to getting it to fire meanwhile incrementally adjusting the velocity with no results. IIRC it just hissed out the back when I went far enough.

Any other thoughts? It's been quite a while for myself.

i had the same thing when i installed my Level 10 and when i did get it to fire i had to crank the velocity up so high it was leaking out the back of the valve. Here's what was told to me.

Worth noting i tried the fix suggested but haven't had any air to be able to test it and see if i am fully corrected.

You can turn in the reg till it bottoms out, there no such thing as too much. If your leaking out the back and still not fireing you'll have to purchase a new piston or perform a little maintenance as was said by Bigwooly. Just follow what I said in the link. If it doesn't fix your problem, you'll need to purchase a new piston. I'm going to see about making a video or just a picture show of how to do that maintenance at work tomorrow if were not too swamped and I'll get it on youtube for you all to see.

ok the regulator piston assembly's o-ring has scores on it which could be the reason why its leaking out the regulator nut. does the new reg piston assembly come with a new o-ring or should I buy a 4 pack of it?

[Ando]

I don't know if it does. Try using your lvl 7 spring with the lvl 10. It should fire without having to adj the reg to much.

So I just installed a lvl10 bolt and I'm kind of stumped. watched the video and can't seem to isolate the problem. I am new to automags but feel like i've troubleshooted pretty well. prior to installing the lvl10 bolt i had no leak down the barrel but was experiencing bolt stick (the trigger wasn't resetting) figured instead of buying spacers, i bought a level 10 kit.

after installing the new bolt using the carrier w/ 2 lines and 2 shims to start with, I was originally getting no leak down the barrel but the gun wouldn't fire. the trigger reset but pulling it did nothing.

took it apart and tried it again but now I am getting leak down the barrel with the trigger depressed or without. That would signify a problem with the regulator right? but the reg was working leak free before the level 10....

all of this while its still not firing.

please help!

First off, remove the level 10 shims when tuning your level 10. That way you won't get any false leaks. You can put the shims back in later if you wish. You will probably never need them.

Start with the standard level 7 bolt spring (a new one). It will allow you operate the gun at its lowest velocity setting. When changing carrier sizes, always use the same white powertube oring. Its this oring that the carriers are adjusting. Use the largest carrier that does not leak. That means you install increasingly larger carriers until it starts leaking. Then go back to the one that didn't leak. Don't forget to increase your velocity/pressure setting. The level 10 operates at a higher chamber pressure so your previous level 7 settings may not allow the gun to fire. Because the gun operates at a higher pressure, you may exceed the pressure release threshold of the regulator piston assembly. If this happens, you will need to get one of the new higher pressure assemblies.

Slight scoring on the regulator piston assembly shouldn't cause the leaks. It would leak all the time if it was the cause, not just when you increase the velocity. Generally, you will get a leak out the back when you increase the pressure past the safety release value. You will also get a leak when you back it off too far. There is a vent hole that allows air to pass once the piston oring is backed out past it.

For the record I do believe it was ando who gave me the suggestion about taking the regulator assembly apart and turning the rubber piece in the bottom of it over. Well this worked and mine is now cycling just fine with the velocity cranked all the way up and with the Red Spring (middle one)

[jinhao]

majorho had a spare regulator assembly so I stole its reg piston and swapped it with mine. no more leaking out the regulator anymore. I put it on with the lvl7 spring and it still won't fire. on/off pin still resets but nothing happens besides that. will using the older lvl7-tuned regulator piston cause it to not even fire at all? I cranked the regulator all the way in and it still doesn't fire.

any other thoughts?

If the on-off pin is pushing down on the sear such that it is open and air is getting to the chamber, then it should fire. The only reason it wouldn't fire is if it had bolt stick due to a carrier that was way too tight.

Remove the barrel when checking your operation just in case the barrel is off centered and causing excessive friction on the side of the bolt. This could also be true if the body pim was too long and bottoming out in the rail. Also make sure the rail bushing is in place.

[jinhao]

not sure where the rail bushing is but would this be unique to the lvl10? the gun fired fine w/ a lvl7

It probably isn't the problem, but something to check if you had the gun apart. The rail bushing goes in the rail where the rear field strip screw is. If it is missing, the valve could be out of place and it won't fire properly.

Sort of a level 10 problem I think. I just got a ult and tried to install it but after a few shots the marker would just start venting air down the barrel, so after toying with that for a good hour I decied to switch back to the old RT on/off and see if it that worked.

I gassed up the marker an pulled the trigger once and it fired like 3 times before the bolt got stuck in halfway into the chamber and the marker started venting again. I also oiled it before the tests

Any ideas are much appreciated

Did you try it shooting it again with the stock on/off? Might have just been a fluke if the marker was shooting fine before. If it's still sticking.

1. More OIL!!! Toss a few more drops in the fitting (i prefer topping off the fitting) attached to the valve itself. If you put in your asa or whatever you have, it tends to thin out before it gets to the valve.

2. Install a new/different bolt spring. A weak spring will sometimes do that.

3. How many Lvl X shims you have installed? Try removing 1 and sally forth then repeat again if still doing it.

Get the lvl 10 working with the stock on/off before tinkering with the ULT.

EDIT:

On/off Orings are good right?

Ya they look fine, and I have 2 shims
