2nd time I've had this problem with the rotor, Paintball stuck in the feedneck of the rotor. Pulley switch thing no help had to take off hopper and poke it back up then remove all the paint to find the damn big one. I'm thinking getting a bit of sandpaper in there and trying to widen it a bit. Anyone else had this problem or have a better soloution before I start rubbing bits off my £120 loader.
