The spool valve is the red wire thingy on the noid...
I was thinking about one thing...I have an Eclipse QEV in my Ion, and I can't really understand exactly WHAT it does?
It vents the air out of the gun instead of sending it back to the noid, right?
Does the air come from the bolt-chamber and just goes through the banjo and back to the noid originally, or is there air coming in through the hose, and then goes back to the noid?
Because if it's like alternative one - the air just comes into the banjo from the top, and all the banjo is supposed to do is send it back to the noid - then instead of a QEV, I might as well just take out that banjo, right?
I might be misunderstanding the whole thing here, since I don't know much about internals, but if so....enlighten me
