what seem to cause this? i tried step one. after the solenoid closes the HP gauge stays at 1000 psi but the low pressure gauge goes up to 50 psi.
my problem is that when the solenoid open the pressure at LP gauge drops until nearly zero but the JP gauge is still 1000psi.
this leak check is not going to work on your regulator.
anyway, the picture shows how your paintball regulator work. it is similar to a single stage pressure regulator, but without
diaphragm, and yes, the spring would keep it at 50 psi output, but without a diaphragm, the friction on the piston will cause problem which is what you are experiencing at the moment.
