Did you cock it before airing it up?
Are the seats flat on the valve caps? Seats are made out of either translucent urethane or white delrin. If you have one with a buna oring in it it isnt mine and it wont work.
Urethane seats are a 012 oring and are held in place with loctite brand " crazy glue". The gel in the black and blue dispenser.
You can clean up any rough spots on the power tube. Stay away from the sealing face.
Also check the 010 buna oring on the power tube tip in front of the washer. It might be damaged.
