** Official Level 10 Problems Thread **

I have a micromag rt running off of a 3k flatline. I put a level 10 in it a couple of years ago. It worked perfect for a couple of summers. Lately the gun still works fine but when I let off of the trigger there is a slight leak coming from the back of the valve (where you make the velocity adjustment) The gun is set to shoot at 285 fps input pressure from the tank is 1200 psi. The gun works great, and the leak goes away if I hold the trigger in the firing postion. It has been quite a while since I put the level 10 in. I don't remember how to fix this. Any thoughts?
Thanks,
Kory

This leak is caused by a worn regulator piston assembly. The retro valve uses an air passage from the front chamber to the regulator piston assembly to provide feedback for pressure regulation. When you hold the trigger in, you prevent the pressure from getting to the piston and overloading the weakened piston assembly.

Looks like I'll be ordering a regulator parts kit from the agd store. Thanks for the info.

Well, after reading through all 46 pages I saw plenty of others ask this question but no answer. With the level 10 instlalled in my ReTro Valve Micromag the reactivity is almost nothing, it's like shooting a classic valve mag. When I take the level 10 out the reactivity is back and very strong. What is the level 10 changing that's making me lose my reactivity, and is there a way to fix this? Thanks.

lvl 10 on field rental

hey guys, ive been trying to tune the level 10 on a friend's 68 automag when i noticed that its a field rental automags and in the agd website it said the level ten isnt compatible with field rentals. the thing is I had it shooting with no leaks with the .5 carrier and no shims, standard spring; but the bolt didnt look like it would not chop a ball in half. is there anyway to make it work, or is it hopeless? thanks

There are a couple of things that change the reactivity of the valve. The higher chamber pressure required by the level 10 affects the trigger pull by increasing force on the on-off pin but the level 10 also reduces the force on the bolt. Depending on your setup, you could get varied results, but the reactivity will be affected. Reactivity depends on the differential force between the trigger pull and the force of the recharging air. The level 10, operating at a higher pressure increases the required trigger force, but the residual pressure remaining in the chamber is higher as well. The higher operating pressure also makes the differential pressure between the chamber and bottle less. The recharging air has less force acting on the top of the on-off pin. The total result is less of a differential between the forces of the pull and the return. Thus, you get less reactivity.

Check the powertube. Field rental valves had a restricted passage in the powertube. If your valve does not have a restricted powertube you are good to go. If you have been firing the gun with the level 10 bolt and it fits in the powertube, chances are you have a regular valve.

it looks like it gets a little narrower right after where the delrin washer sits. in fact, that makes the washer kinda useless cause theyre no way the power tube oring would fall through there...well that sucks new valve for me!

lvl ten and minimag valves

hey guys i was wondering if the level 10 works on minimag "reverse" valves. Also, when tuning the lvl 10 on a regular classic valve, what is the most advantageous way to adjust the spring? is it best to try and get a short one to work, long or middle? Thanks

The level 10 bolt works on all mag valves.

When adjusting the sensitivity, use the longest spring you can but make sure it gives you consistent operation. The middle spring seems to work best for most people. Remember to remove all shims when setting up your level 10. Once you get the proper carrier setup and the proper spring spring installed, you can add a shim or two to adjust the vent hole distance. A lot of people never use shims at all. I don't and have never had a problem having fired well over 100000 rounds out of my emag with the level 10.

squeegee test?

hey guys, i just finished tuning the level ten to my minimag classic valve. 1.0 carrier no shims, middle spring. i shot about 60 rounds and no leaks shooting consistently...but when I did the squeegee test putting it front of the bolt, it comes forward, hits the squeegee slightly vents and bounces off...is that what it should do? im just trying to gauge if i tuned it correctly to not chop..

also just a misc question, my minimag valve on top says Center Fire Mag #0133 what is the significance of that?

thanks

That is exactly what it is supposed to do.

RT level 10 leak

I have an RT classic and I'm trying to install the level 10. I followed the directions and got it to fire with the 2 lined carrier, but the gun leaks out of the back of the valve, right where you adjust the velocity. If I turn it up too high it squeals, maybe it's the shims? I'm using the medium spring, 2 shims and the 2 lined carrier. The leaking continues with all the smaller carriers. Please help!!!

The older classic valves (RT and AIR) have lower overpressure settings in the regulator piston assembly. The level 10 operates at a higher chamber pressure which combined with aging parts of the assemby is too high and vents out the back. The solution is to get a new regulator piston assembly. the new ones are rated at a higher pressure for use in the level 10 equiped valves.

Where do I get that, directly from AGD?, cause I looked on their site and couldn't find it. Thanks for the help though.
