Need Karta/Pneumag help

[Butros]

Alright guys, this thing is kicking my butt, and I figured if anyone could figure it out it would be you guys. So here goes......

I sold a Freeflow Shocker pneumatic frame to a friend of mine that wants to make his Karta body and rail a pneumag. The frame worked great on my RT rail and ULE body, with X-valve, no problems. He brings me his body and rail and I put the gun together with a classic valve(which he wants to use), looks great. Air it up and NOTHING. The ram will not trip the sear at all. I cannot even trip the sear with a screwdriver, it is STIFF.

So I figure it's the valve....NOPE. Put my x-valve in it, the same one that this frame was working with all along, and same thing, cannot trip the sear. So by process of elimination I assume it's the body and rail combo right.....NOPE. Put it all back together in my original configuration(which it hasn't been put together in months) and same thing. RT rail/ULE body, X-valve, same frame setup, NOTHING--Still cannot trip the sear even with a screwdriver.

The only thing I can figure is that I cannot find the same forward grip frame screw that I used when I had it put together, this one is a hair longer, but it tightens all the way. Is there any way that this screw is TOO long and it is tweaking the body or something and not allowing the bolt to move forward?

PLEASE HELP!!

Your on/off pin is probably too long. Is the body rail a single piece? Usually you could just loosen the field strip screw so there is a tiny bit more room between the rail/valve, but if the body and rail are a single piece, no dice. You'll have to either buy a shorter pin or file yours down a little bit.

[Butros]

Thanks Xero. No, body and rail are not one piece. I will give that a try, but the problem is that just a month or two ago, I had this thing set up on my body/rail with no problems. When I set it back up that way, I still get nothing. I am going to get some more air tomorrow and fiddle with it again, so any more options to try, keep them coming, I'm open to anything at this point.

Please help, I really dont' want to have to "buy" this back from this guy.

Is everything working fine with a mec frame?
Have you tried adj the pressure on your LPR?
Is the ram even moving when you pull the trigger?
What kind of kit do you have?

[Butros]

It's a regular MSV-2 kit. LPR all the way up it won't trip sear, never been a problem before. The ram moves, hits the sear and stops......I cannot even trip the sear with a screwdriver.....I'm stumped. I have not put a mech frame on the Karta body/rail combo, but both valves work fine when in my RT setup with mech frame no problem. But if I put pneu frame on MY RT body/rail it does the same thing.....

Have you tried tripping the sear without the frame?

Just throwing this out there... it could be that the ram is positioned in such a way that the front of the sear is hitting the top of the ram, preventing it from pivoting.

any luck with this?

Good Call!

That was going to be my suggestion. With the rail on and the body off does the sear move properly. There should be enough room between the top of the mpa-3 and the bottom of the sear for the sear to become flush with the top of the rail. if this does not happen be sure to create enough clearance for this to occur. What rail and sear is being used and is the sear the same as before when you owned it?

Please update us.

How will I trip the sear with no frame? Put the thumb screw in to hold the valve? I hadn't thought of that.

So both my valves I currently have, a classic and an x-valve with NO ULT. Months ago, my factory RT ULE Custom with this frame on it worked excellent. I took the frame off when I got my airwalk. Got this Karta body/rail, put the classic valve and the pneu frame on it and this is what I get. The ram is hitting the sear squarely and the entire face of the ram is hitting the sear....but no fire.

I put my X-valve in it, same thing. So I thought it had to be the body/rail combo so I took it all apart, took my airwalk off my RT and installed this frame and Classic valve...nothing. So it has to be the classic valve right.....nope same thing with X-valve.

So I am TRULY at a loss.

I will go home tonight when I get off work and try and hook it up with no frame.....IF I HAVE AIR> If not I will have to get air tomorrow and check it out.....

ANYTHING ELSE? I'm up for ALL ideas!

Oh and I will take some pics maybe a vid or two.

hmm is the velocity turned up enough, do both valves have lvl 10, maybe they are dried out a little and just sticking making it not fire. sorry if these have been covered i didnt read all the posts.

[Butros]

Definately well lubed. I have been running both these valves in other marker configurations for over a year now. Both have LVL10 and both function fine in other configurations without the pneu frame.

And velocity adjustment has no effect....I tried that.

[reckid1986]

ok does it have the correct sear in it? put the body and rail together and just move the sear and see if it moves freely. then put one of the valves in the body and make sure the hole lines up with the on/off, maybe something could be off there, very unlikely but make sure. have you tried your airwalk frame with the karta? check your air lines in the shocker frame maybe one is kinked and not letting enough air through? is the mpa3 set so it will push the sear far enough? does the sear move easy with the frame installed and no valve?

i cant think of anything else right now....i set my karta up with my pneud-intelli and every thing lines up and works just fine. You have an odd situation here. good luck
