KWA G17 Issue/Problem

[thecandyman]

Alright. Well I just bought a used KWA G17 and its not working. There is not enough gas getting to the blow back so it will not blow back let alone shoot. It makes a pfft sound when shot when level with your arm. When pointed at the ground it will blow back twice or so then make the pfft sound again. I have been told that the floating valve might be broken but I don't know what to look for in a broken floating valve. Or at the matter even the problem. I have some pictures of the slide and frame if that will help. Please someone let me know and try to help. Thanks

Yup sounds like the valve spring may be broken or not in there or something, or the other way around and it's too strong(not too sure). Either way, get it to someone who knows how to take it apart and fix it.

How am I supposed to get the valve out there is like a little pin in front of it I don't want to break. Also are you referring to the 2 springs on the side of the piston or whatever?

[Styrak]

No, spring and valve inside the nozzle.

Alright I am pretty sure I know what you are talking about now. How am I to get the pin out that's in front of the valve inside the nozzle is it glued in or what?

[Styrak]

There's either a small screw or pin you have to take out to get to the nozzle internals.

[thecandyman]

Alright going to take a look right now. Thanks

[thecandyman]

Alright well after like an hour of trying to get the pin out and I finally did. What I found was this:


It is missing part number 27 of the parts list. (Gas Chamber Seal) Does anyone know where one could be purchased. Please let me know. Thanks.

OK I need help, I have a KWA g17 gbb and I just replaced the inpact hammer block..now when I shoot it, I first insert the clip and cock the gun when I pull the trigger it goes pfft... I think the problem is that the button on the clip is not being pushed down all the way, letting very little gas out PLZ HELP ME

Next time dont buy a broken gun unless you know what's wrong with it. It's not cycling because your nozzle is too loose, therefore your piston cup cant push the air. That's the reason why its not blowing back and the trigger that hits the output valve would only stay in one spot to release all the air (thats the hsss your hearing). You need a KWA g17 nozzle, not the KSC glock nozzle. Its gonna be hard to find parts, if you can call KWA and able to do a special order on your G17 parts then your good to go, If you cant then your shit's out of luck. If you have enough money try to replace two things piston head (or your so called air seal chamber) and the right nozzle for your gun. I hope this can help.
