Took it apart replaced valve stem and head and the seal underneath the head. Replaced the seal on top of the nailer piston. I probably didn't need the valve parts and definitely didn't need the o-rings in the parts as they were part of the valve stem.

One o-ring went bad. Replace that but the main problem was a piece of the old o-ring was blocking the exit port. Blew it out with an air compressor and now the nail gun works great.

I disassembled the trigger by first taking out the pin and then removing the throttle piece of the trigger by increasing it. After it was removed I placed my hand over the hole and lightly connected the pressure hose to blow out the rest of the parts. I replaced a deteriorating seal and reinstalled.
