68 Classic leaking air

[SonnyB]

Just purchased an older automag that seems to be leaking air from the valve. When first engaging your tank there is no leaking and then after a few shots you can hear the hissing. When you increase the velocity the hissing gets louder. Please help. I think I may need to replace the valve o-rings?
Thanks

when the velocity is to high, it will leak out of the valve...turn it down. where in stockton do you live?

I'm pretty sure that it was leaking no matter how low it was. I went as low as making the bolt move only a 1/3 inch or so. Thanks for the heads up I will try a full tank.
