Glad you found the oil and purged it. Generally if you put a charge of lacquer thinner in the gun and shoot it through it should clean out the critical areas, but with anything made in China or the Pacific Rim and shipped in you may have some pretty heavy preservatives, like cosmoline.

I'm still not sure what caused my problems, but I bought a new gun today and it shot primer great. In defense of the Harbor freight gun, I did buy a gun mounted regulator with this new gun, and I had not been running one before so I really have no idea what my pressure was at the gun with the drop through a 50' hose. As I was headed out to the shop this morning I did notice this on the counter that seemed to be appropriate to my problems. I don't think we'll buy any more of this stuff, just in case .....
