Whats happen is it seems to cycle very slow .... will fire on the first pull but then it will sound like its short stroking or venting till the trigger is released and then it will fire ..... i dnt know if my lpr is the problem being it came off my eblade and i had it hooked up to my etek mag i was very succesful at building .... so all you mag addicts out ther help a fellow brotha out Thanks

is the ram too close.
its good to have about 1/8th of and inch space.
start there.

as well its all mounted to an intelli of course , i thought maybe the hose going to the ram was the caus ebut its not catching on the valve arm at all even tho it looks like it is , and the last pic is of course my Etek 1 mag i built and shot and performed like it was right out of the box ! So guys plz help a buddy out here ......

if you can maybe reposition the msv2.
it looks a little wide.
but then again all my activation ares are all cut down.

**knownothingmags** · 02-09-2012, 11:43 PM

oh you need a return for the trigger/msv2 arm get the magnet mod made up.
thats what fixed my problem about 2 yrs ago.
it has to wait for the stuff to reset thats why its chuffing.

i just saw you dont have a return for the trigger.

if you want to send it to me i can tune it for you.

but that should fix it.

let me know what happens

**Scooby_Z** · 02-09-2012, 11:51 PM

thanx for the advice .... Im sure i can whip up a magnet mod , and yeah that seems to be whats happening is that chuffing ther will attempt that tomorrow after wrk and I'll have a response.....thanx man

you need to adjust the MSV position

the best way (for me) to set it up is to air up the marker, slowly rotate the msv forward until it just barely starts to vent/hiss and then back it off just enough to make it stop venting.
tighten down the bolt

a magnet mod will help a lot too. I'd suggest getting one from mag79 if he still has any left.

another option is to shorten the msv lever and place it higher in the frame. this will make the pull a lot shorter too and the trigger a little snappier and less spongy. The downside is that it does require cutting the lever. If you cut off too much to the point where the trigger pin no longer makes contact, you'd need to buy a new msv2 (or hope to find a replacement lever)

Good luck!
If you get too frustrated and would rather have someone else do the work, contact Loguzzz or mag79. Although you learn a lot by working on it yourself and you can fine tune it exactly to your preferences.

Try this before you adjust your MSV-2 position.

Can you actuate the MSV2 with your finger for multiple cycles? If you reach in with your finger or take a pencil, can you get your marker to cycle multiple times in a row? If you can do that, I think it would be the position of your MSV2 and lever. If you are still having cycling issues, it might be that your LPR has to be turned up.

I ran into this on Saturday where I could rip a good couple of strings and then it sounded like I short stroked every couple of shots and then just vented in the MSV-2. I was using a Tickler and found that the adjustment knob backed off quite a bit. Once I tightened it down and increased the pressure, it would cycle consistently.

And I'm not using a magmod either

You should set that up to 850 before you get too far. Even if it is not your problem, it can affect your lpr response.

You will also need the pressure when it gets up to speed.

Just like a good email chain... start from the bottom up!

The etek board has DWELL which will reset the ram everytime. The gap between the ram and the sear should be approximately .125". This will give a little more gap, simulating DWELL. What happens is that even though you feel like you are fully releasing the trigger but the on/off is not resetting due to the lack of a gap. I call this a lazy finger. Walking a pneumag is an art, not nearly as easy as an electro. Once mastered you will actually be faster with an electro as well. Practice walking the pneumag often and you will get better at it.

Another problem that I see from your pciture is that you have the trigger rod pointing up hill away from the msv2 this forces the msv2 to work harder to lift the trigger rod. The magnet return will help this. In the future try and keep the trigger rod more level. I use aluminum for the trigger rod, less weight equal less work. A better quality LPR can help too but is not necessary. I use Ticklers and Bullet lprs all the time with reat sucess.

Be sure that your valve is not the problem by trying it out in a mechanical mag but most likely your problems are due to the statements listed above.

850 psi will not hurt either.
