how often do you do valve adjustments?

my screw driver does the same thing.

True. There are more than one way to skin a cat. I like to rotate the cam by turning the rear wheel in 5th gear while listening to the whistling.

What does TDC have to do with valve adjusting?

Just need the cam lobe to not be pushing on the rocker?
