LCS Air Arms SK-19 30 cal air dump

[blackdiesel]

I was out shooting my SK-19 and all of a sudden all the air began blowing out the barrel and magazine area. All the signs of a blown poppet valve in a regular PCP, this is my 1st hammerless so new experience. I was about the reg pressure so that's not the issue. Any suggestions?

Slow? Brocken firing valve. (Like poppet)
Instant dump then stop? Letting pressure get too low and/or magazine jam.

Not slow at all. All air rushed out until the tank emptied. When I tried to put more air in it rushes out too.

Check for a jam, which causes the closing valve to stick open.

Sounds great. I will check it today. Thanks

The two things I know will cause this is too high on power wheel or a jam in the cylinder rotation.

A jam in the cylinder can be caused by 3 things that I've found. improperly seated rounds, the cylinder release lever in up position or barrel screwed in too far.

Did you ever find the culprit?
