Hey guys, when troubleshooting valve leaks, I recommend removing the ram and trigger frame assemblies from the gun. If the ram/carrier is not latched on the hammer, then gassing-up the gun will make the valve leak and never build the pressure needed to latch. Soapy water and a spray bottle work wonders when sniffing around for the leak. First get the valve to seal, then put the ram assembly in and test that.
Likewise when troubleshooting cycling issues, leave the trigger frame off so you can see the carrier and hammer move. This will tell you a lot...either its not latching or its not tripping the sear.
