I have been having some chopping issues lately, and I need some help. I don't think it's due to paint or temperature because both of the times I chopped paint, I was indoors. Anyways, the first time it started chopping, and I couldn't figure out anything to cause it. This time though, it was shooting fine, until after a while when I was about out of air, it started to chop. So I took apart the gun, and after cleaning out all the paint, I found this:
The white oring thing (which for me isn't a white oring thing, it's just a plain oring) at the bottom arrow was up where the second arrow was or higher up. Is it okay to have an oring instead of the white bumper, and could this cause chopping? If not, what could have? Thank you in advance.
