I made that system back when I was a teen :lol:
For it to work you need a piston that has spring in the back and allows to be filled from chamber side.
If your QEV is bought un modified, take a 1mm wire and poke a hole in the piston (not in the middle or you get leaks, poke it where the thick rubber meets with the rubber skirt), then add a weak spring behind it. Then it should work.

I came up with a similar design too as my first "semi auto".
The idea is to limit the exhaust volume so the QEV would close. I made a check valve with tiny leaks instead of the shrader so I don't have to manually reset the shrader.
Basically one side of the blowgun connects to the QEV the other side has to have a valve, be it a shrader, ball valve or check valve. You can play with the exhaust volume too for different output power from the QEV

You still need the hole too.
The QEV need modification in all cases, except when you're using a 3 way/slide valve setup.

Another question, I want to make hole and add spring but i want too to shoot one shot with this? Will hole and spring deacrese power with one shot? With spring and hole can i fill the chamber from pilot port? or only from chamber port?
