My 3 point adjustment knob, located under the seat, will not turn any more. It seems to be stuck in one position. It will not turn either way. Any ides?
The way that I have done it is to soak with PB Blaster where it goes into the housing. Let it soak for a couple of days. Then use a pair of vice grips very gently on the shaft.

Yes, it is. I haven't bought WD-40 for a few years, because PB Blaster is that much better.
