help with 68 classic

[welle_k]

I would like to ask for some help, a couple of weeks ago, My air did not shut off when I pulled the trigger, I replace the on/off switch, that did not work, I thought i could not find a power tube O-ring, so I put in a level 10, but i still does not work. I searched everywhere for O-rings that are broken, but did not find any

Is there any fixes that you know of, or is there a place in central Minnesota where I can bring it to get it fixed?

where is the air comming out? Down the barrel?

yes the air comes down the barrel, when I puch in the trigger, it slows down but does not stop
