Thanks Doc, So what should I think if mine was all the way in(no gap between locknut and adjusting bolt), to begin with? Also, should I replace mine with the newer better bolt. Mine has a wear mark on the end of it from where it touched the rack all this time. If I start at the basic adjustment spot, and I keep having this rough idle when I come to a stop, should I keep turning it in a little at a time until it no longer does this? Thanks So Much!
