I've got a palmer microrock on my 2k3 mechanical cocker and lately it's been spiking pretty bad, almost like it's not regulating at all. I put some oil into the reg, but no luck it keeps spiking. So I want to take it apart to check the orings however I'm having a hard time opening it. I took off the adjustment screw and the screw connects the reg to the front block. However, to unscrew the cap from the body do I hold the cap then turn the body clockwise or counter clockwise?
