Left unable to bench sync the butterfly valves, I finally pulled the bolt out only to find that it was in clearly bad shape. When the nut reaches a certain point, it just won’t go any further. On my carbs, the nut is threaded, and so too is the mounting point on the rod (that the butterfly valves attach to). Running the nut up and down the bolt (viced in) cleaned it up, but when it goes through the rod it gets “screwed up” again. Looking closely you can see the rough edge after going through the mount point on the rod.
Kind of a funny way to end the semester, but knowing that it will get repaired “right” makes me feel pretty happy. On the way out noticed a nice placard on the door, too.
