68 Automag help

So my friend asked me to fix his automag, he said it had a problem with the valve.

So I took it apart to look at it and all the seals looked fine and it hold air very well. No leaks or anything. Problem is that it won't shoot. I took the trigger frame off and I think the issue is with the seer. Is there supposed to be a spring behind the trigger or trigger pin? I haven't ever seen an automag internals up until this point.

Help is appreciated.

no spring is located behind the sear, it is the pressure of the on-off when the valve is aired up that holds it tight against the trigger. if the pin is not sitting tight against the back of the trigger when the marker is aired up and at rest it sounds like the on/off isnt working. on the other hand, if the on/off isnt holding the pin against the trigger I would expect it to be leaking down the barrel, not holding air at all.

From what I have seen, which is only one minimag, there should be so springs other then in the valve and the twist lock

You try turning up the velocity?

Second Ando.

If the regulator nut is not at least snugged, you will have a pressurized marker that doesn't leak but does nothing when you pull the trigger.

De-gas the marker. Stick the long end of an allen wrench in the regulator nut and slowly dial it in using the short end. Does it turn loosely, or can you feel it turn against spring pressure? If you can easily turn it you need simply to dial it in until you feel it just begin to snug up. Turn it an eighth or so beyond that and then gas it up.

Does it shoot now?

Try turning the nut in just a bit more. The regs on the mag are very sensitive. Just a slight turn will go a long way.

I only suggest this because my own did it the very first time I gassed her up, and it freaked me out. Soon as I turned in the reg, however, she fired up and ran like a champ.

See if that doesn't help. But I'm just a mag pup myself, so better to listen to the big folk in here.

Check the distance between the trigger and the sear pin. There should be a space the thickness of a credit card between them when the gun is aired up. If the pin is too far forward to the point were it is actually touching the trigger, the gun will not be able to cock properly. If the pin is too far back it will not be able to release the bolt/trip the on/off.

Do you know which bolt (lvl 10 or lvl 7) it has?

If it's a stock x-valve it will be a level 10, if it is a stock classic, it will be a level 7.

If it is a level 10, you could search for "bolt stick" and go from there. Turning up the velocity can make the difference.

People often take the reg apart for cleaning and forget to count turns on the adjuster or just not realize that they need to put the velocity back to where it was.

Stock valve, stock gun at that. It had a tourney lock on it so I turned it up and it fired.

Now the new problem. It was leaking down the barrel. Help? I'd like to not have to guess at it because I've only got 1200 psi in my tank and only have that to test guns.

Hold the trigger down if it still leaks its the on/off if the leak stops its the power tube or orings on the barrel.
