Leak down the barrel

[TencenT]

Trying to chrono and my Karni is just going wild +- 100fps and then constant leak down the barrel. Threw it back in the gear bag and this is what I found taking it apart today. Hardly seeing a problem here. Valve stems are supposed to be 10 pieces, right?

Looks fine to me; you check to make sure you were using summer air and not winter air?

[TencenT]

I was definitely using the right season of air but I may have accidentally used a southern hemisphere 9v instead of a northern. Rookie mistake.

Oh man, what valve is that?

[TencenT]

Genuinely no idea, I have a few in the toolbox and this one ended up in my hand first. Just ordered a Lazarus valve to try that out though. If that ends up not being good I'll just move on to the next valve I guess.

Wgp plastic cupseals are not aging well.

I've had three fail on me this year

Unfortunate

I don't see anything wrong. Did you try adding oil?

Orrcale valve and springs. Set the reg at 250 and the IVG # 3truns in ......300 FPS back out IVG 1/2 turn 285

Ordered a laz valve and I'll try one of the lightest hammer springs to see how that goes with it. I do have some other valves I can use if it doesn't work out.
