check the seal on the poppet good, even a really small piece of grit or dirt will do it...use a magnifying glass and look close, also the same with the cap...
Decided to pick up the MM PCP and take a quick shot out the back door. Zero air pressure. Must be leaking down because it had about 1000 psi 24 hours ago. So, I pumped it up to 1500 so I could check for leaks at the kitchen sink. No bubbles from the fill cap or nipple, but a steady stream of bubbles was coming out the barrel. What's the best way to fix this leak?Thanks in advance, Bill
