Rocker studs snaping

Guide plates off so far the roller is less than halfway on the valve tip. Inexpensive rocker twists a hair and the adjuster hits the corner of the slot making the witness mark. Pop goes the weasel. Fix the guide plate alignment. Sharpy the rocker slot and see if a shiny spot comes back. Putting a high quality stud on will probably just break something else. It’s definitely talking to you!
