What do I do?
Degas the reg, or at least make sure ithe on/off is off. Unscrew the retaining nut (the one on the opposite end to the spring cap, which takes a fecking big allen key.) Remove the poppet guide (brass bit with o-rings), spring retainer (another brass bit), spring and poppet (the pin thing with a cone-shaped bit.) The next 4 bits to come out comprise the seat (seat cap, white o-ring, seat base, black o-ring.) Make sure these two o-rings are spotlessly clean, and do not have any nicks or scratches. If damaged, replace. Reassemble without lubrication, except a light film on the two o-rings on the poppet guid (the last brass piece to go back in before the retaining nut.)
That should clear up your hot first shot
