I've had many tech problems and this one is no exception. I split open my receiver to see what the gearbox does when I fire it. In firing it I've seen that the air nozzle is barely moving back and forth if at all. However when it does move it's like a big "jump" back and forth and then it won't move. Can anyone give me a possible solution to my problem? I also believe that this is why my gun misfires/dry fires and doesn't shot BB's properly. I thank you for any and all information that could help me, if all else fails I'll have a tech look at it this weekend at the Kalamazoo Airhouse.

There are a few ideas with the broad description given that comes to my mind: -air nozzle/tappet plate ridges may be broken, thus the movement of the air nozzle doesn't line up with the tappet plate.
Look at the opening around the airnozzle, and you should be able to see the edge if the tappet plate that holds the air nozzle. You should also be able to see the back end of the air nozzle, which has a larger portion of which should be flush with the tappet plate, which would be connected at the bottom.
If everything is all attached properly, you should be able to push the air nozzle back, and it should be like pushing a spring. It will return to its previous position. This is given the tappet plate isn't already pulled all the way back.
-broken or weak tappet plate, or possibly a broken tappet plate peg, on the side of the sector gear
-tappet plate is too wide for the gearbox shell. This can occur if a previous one broke, and you installed another, with out making sure that its width is appropriate for the shell. If the gun is still completely stock, the disregard this idea.
I would need more information to give any other ideas.

Well it seems none of those ideas are my problem. What I can tell you is that the gun is a completely stock and its a JG S-System. From test firing it again at this very moment I looked inside where the tappet plate and air nozzle meet. The tappet plate will shoot forward no problem, but again the air nozzle just sits their.
Off note never buying another JG gun again.

Does the air nozzle move independently of the tappet plate? Is it behind it? Is it in front of it? By the sounds of it, the tappet plate wasn't properly attached to the air nozzle, or the ridges on one or the other have broken, thus not syncing their movement.

The tappet plate moves freely while the air nozzle just sit's their basically. If I would put it on full auto the air nozzle would move more often, but still just sit their.

Can you twist the airnozzle at all, pull it forward? Push it back?
So far, your tappet plate and gears are fine, your airnozzle and where it attaches to the tappet plate are the issue. And possibly the cylinder head, at least with the air nozzle guide part of it.
If you can take your gearbox apart, pull out the tappet plate and air nozzle and inspect the ridges on them, where they connect. If there are any signs if cracks or If pieces are missing, they can't preform their function.

I can't move the air nozzle back or forth what so ever, and I'll take my gearbox apart to check for cracks/missing parts.

Make sure that the air nozzle moves with little resistance on the cylinder head. If you can't move it, pry it off carefully.

Sounds like your air nozzle "froze" on your cylinder head and most likely the tappet plate broke off or slide off of the air nozzle guides.

More than likely, either the air nozzle, tappet plate or both might need to be replaced.

Edit: Figured out why it wasn't shooting correctly. Awhile back I took apart my whole gearbox and put it back together. Unknowingly I didn't put the tappet plate in the air nozzle grove so it wasn't shooting properly. I'll be able to play this weekend!!!!

As I was reading through this thread, all I could think was "Man, the first time I took my gearbox apart I forgot to put the tappet plate back in the air nozzle groove and it wouldn't feed worth crap." Glad you figured it out.

Thank you both it was a relief to figure out the problem, but pissed me off that something so little caused such a big problem for like a month.

I made the same mistake the first time that I took apart an AEG gearbox. I spent so much time trying to figure out what happened. I eventually got it and then proceded to call myself an idiot for the next couple of days. But don't worry, we all do these things.
