Can you overtighten the lockout knob when locking out or doing the opposite? I ask because I took my bike to LBS for an unrelated matter, and the lockout would not engage, and I think the suspension was a bit spongy. The bike mechanic did his magic and now it works fine; only difference is I don't need to turn the lockout knob 180 degrees just 90. I think he said something about it being overtighten which is why I ask.
