It was the fireing valve. What i did was dip the barrel into a bottle of oil and saw the bubbles, i removed the pot and took out the fireing valve, i used a razor blade to remove the ridges and polished the face of the fireing valve. Its been holding a hundred barr for two days. Can you answer me a question. What does the airpot do why is it longer and some are shorter does screwing it in put more pressure on the spring and restrict the air or does it allow more air in. Im going to chronograph it.
