i've been having issues with my 550 primer arm jamming with the pulley/guide wheel going too close to the arm and hanging up. the upper part of the operating rod sometimes come too far out pushing the bottom part too far inwards causing the jam so here was my temporary solution that takes a few seconds to put on and off. i don't go fast to begin with but it fixed the issue except when the loop at the primer tube unravels. the yellow wire prevents the operating arm from going too far out.
