The response trigger technically is not a "full auto" system. Getting it to act like one is a matter of exploiting the mechanism by finding the sweet spot, the location and size of which will change based on tuning, equipment, pressure left in the tank - and with CO2, temperature.

So long as the system is not leaking - which you can test by closing the flow valve under pressure, and trying to shoot it (which you did) - I suggest you start with these:

While you're doing this, remember - the wider you open the flow control, the faster the R/T will cycle, and the smaller the sweet spot will become.
