The control knob on my Cambridge 302 is slightly bent. It rotates OK

best way to do this?

Maybe it's not really a bent shaft.

My 302 became sticky, but only in flight or in winter when it got
colder. Using the point of a pin, I put the tiniest drop of the thinnest
lubricant (LPS 1, I think) I had right at the base of the knob's shaft.
Now it works fine all the time.
