It was still very firm, so I reused the silver bolt and screwed it in until the idle smoothed out. I could do a 1/4 turn on the bolt in either direction and the idle became shaky again, so I locked it down and it's been fine ever since.

My point is, just because the bolt is all the way in, doesn't mean it's beat. Test it first. It was a PITA to remove and replace the bolt due to tight quarters. I had to use two finger tips and start the threads blindly while burning my hand on the operating temp parts.
