I bought a Concours gun. I used it once with the 1.8 needle/cap setup to shoot some Rust Bullet on a few panels. I cleaned it with acetone after the last session with the Rust Bullet and everything seemed good. I pulled it out a few months later to shoot some build primer and when I hooked up the air hose I pulled the trigger and heard a “phuuut” sound and that was it. Nothing. No air coming through the gun.
I’ve completely disassembled the gun, soaked it it Acetone examined all the passages, blown compressed air through it and everything seems to be open in the air passages. But when I reassemble it I get nothing. Have I reassemble it incorrectly or did some Rust Bullet not get cleaned out and harden somewhere to block the air passages?
